The Overview on Inert Glove Boxes and How They Work

For businesses that work with inert gases or hazardous materials, glove boxes are essential. They allow employees to safely work with sensitive or hazardous materials without compromising either the material or their safety. While glove boxes are an effective solution to handling inert and hazardous materials, they are not failsafe. To ensure there are no leaks in the glove box, it's critical to pair a glove box with an oxygen monitor. 

How a Glove Box Works 

A glove box, sometimes known as a dry box, is a large box with at least one window and two ports. The ports allow workers wearing arm-length gloves to place their hands inside the inert environment, where they can work with hazardous materials or inert gases, such as argon or nitrogen. 

The interior of the glove box is filled with an inert gas -- usually nitrogen, although it could be argon or helium if the materials used inside the box react with nitrogen. While the glove box environment is intended to be closed, small amounts of oxygen can seep through the glove ports. Thus, it's essential that the glove box be purged nightly. 

There's an antechamber on one side of the glove box. This allows you to place materials in the chamber, then open the interior door and bring them into the glove box environment. To prevent the insert gas inside from seeping out through the antechamber, you must never have both the interior and exterior door open at the same time. 

Inert gases, such as nitrogen and argon, displace oxygen. If these gases were to leak into the air via the antechamber doors or through a hole in a defective glove box, it would push oxygen out of the room. Oxygen levels would begin to drop, eventually falling below the OSHA threshold. 

When oxygen levels drop below the OSHA threshold, it can cause respiratory and cognitive problems, as well as death via asphyxiation. To protect employee safety in a glove box environment, it's critical to use oxygen monitors onsite. 

How an Oxygen Monitor Protects Your Workers 

While your staff might see the antechamber doors open and understand that a leak has occurred, most leaks are undetectable until it is too late. 

Inert gases have no color or odor, so there is no way for someone working onsite to know at a glance or sniff there's been a leak. Meanwhile, the air in the room would slowly lose oxygen, eventually leading to an oxygen deficient environment that places your employees at risk of death by asphyxiation. 

A wall-mounted oxygen monitor samples room air 24/7. The monitor remains silent if there's sufficient air in the room. If there is a leak of nitrogen, for example, and oxygen levels fall, the monitor will sound an alarm and flash lights, so workers can see and hear there is a problem. 

Your employees will be able to leave the room before suffering adverse health effects. Staff will also be able to complete shifts with less stress when they know the environment is safe, because they trust the oxygen monitor is working properly. 

PureAire's oxygen monitors feature long-lasting zirconium sensors. Once installed, these oxygen monitors measure the oxygen in the air for 10 or more years, without needing annual calibration or maintenance. The monitors are unaffected by sudden shifts in barometric pressure or thunderstorms. The digital display provides legible, updated oxygen readings so employees can check ambient oxygen levels. PureAire's oxygen monitors can be used in confined spaces and in temperature extremes as low as -40 Celsius. All PureAire oxygen monitors come with a three year warranty for your protection. Review specifications or learn more about oxygen monitors from PureAire by visiting www.pureairemonitoring.com

Storing Liquid Nitrogen in Laboratories: Which Safety Precautions and Sensors Will Protect your Employees?

https://www.pureairemonitoring.com/

Liquid nitrogen is frequently used in scientific research, chemistry classes, and even culinary arts nowadays. The substance is safe when properly stored, and as long as everyone follows safety protocols while handling the liquid nitrogen. As part of an environmental health and safety review (EHS review), learn safety considerations regarding storing liquid nitrogen in the lab setting. 

EHS Review: Understand Liquid Nitrogen Risks

Liquid nitrogen is known for its cryogenic properties. It can freeze things incredibly quickly. This property also applies to people, so staff must take safety precautions when handling liquid nitrogen. Even seconds of exposure can damage skin and eye tissue, and may cause frostbite. 

Staff should never transport liquid nitrogen in open containers. They should never reach directly into vats of the substance. 

The main health risk with liquid nitrogen occurs when the liquid vaporizes into gas, which happens if it leaks into the atmosphere. Nitrogen expands in volume when it turns into gas, and depletes oxygen from the air. The gas has no odor or color, so there is no way staff can tell a leak has occurred without an alarm system. If a nitrogen leak occurs, oxygen levels will fall below safe thresholds. This causes severe cognitive and respiratory problems, as well as death by asphyxiation. 

Liquid nitrogen, like other cryogenic liquids, needs a pressure-relief valve during storage. Without such a valve, internal pressure could cause the storage tank to explode. Liquid nitrogen should be stored in a room that has proper ventilation as a precaution around leaks. If a leak occurs, the ventilation system can help shunt gases outdoors, protecting the health of workers. 

How to Protect Your Employees' Environmental Health and Safety With an Oxygen Monitor 

Facilities must install, calibrate, and maintain oxygen sensors to comply with safety policies regarding the storage of liquid nitrogen in the lab setting. These units act as a secondary precaution against the dangers of a nitrogen leak. An oxygen deficiency monitor or O2 sensor measures the levels of oxygen in the environment at all times. These devices provide labs with a cost-effective and reliable way to make sure there are no leaks in nitrogen storage areas. 

For safety precautions, install one oxygen deficiency monitor anywhere liquid nitrogen is stored, handled, or used. These monitors mount to the wall quickly and provide continuous sampling of oxygen levels. As long as there is no leak, and the room contains enough oxygen, the monitors stay silent. If nitrogen leaked it would cause a decline in oxygen levels, eventually triggering an alarm and flashing light. The oxygen monitor would provide enough time for anyone working in the area to vacate the premises and avoid being harmed or killed. 

While there are several styles of O2 sensor on the market, those from PureAire are preferred for their high quality and cost efficiency. PureAire's O2 sensors feature zirconium, which lasts for 10+ years on average with no maintenance and no calibration. Once the monitor in installed, there's nothing more that needs to be done. Since PureAire's oxygen monitors are reliable once installed, and require less maintenance than the competition, they make it easier and cheaper for labs to protect worker safety.

University Environmental Health & Safety Departments: Handling Compressed Nitrogen and Cryogenics

*Click here for oxygen monitor details

An explosion at a university research lab in Hawaii last year highlights the dangers of working with compressed gas and the need for safety equipment on campus. Learn the dangers of working with compressed gas, how an oxygen deficiency monitor can help, and campus safety best practices. 

Compressed Gas on Campus: Uses and Dangers

Compressed gases including nitrogen, argon, and oxygen are widely used on campuses. These gases have many practical and educational uses across educational institutions. While the level of risk varies across schools, a few examples will illustrate the benefits and the risks of using compressed gas on campus.

Argon gas is critical in the 3D printing process, which campus design, fine arts, applied arts, and sciences may use. Culinary programs may use liquid nitrogen for cooking and freezing, and chemistry labs may use N2 as well. Autoclaves, which sterilize equipment, are regularly used in scientific, medical, and industrial programs. Sports programs and physical therapy training programs may use cryotherapy for injury recovery. Cryotherapy chambers rely on nitrogen to chill the air. The chambers can turn deadly if a nitrogen leak occurs. These gases may be used by facilities personnel, researchers, faculty members or teaching assistants and students assisting with teaching labs. No matter which gas students are working with, they are at risk if the gas is not handled, used, stored, or transported properly. 

As these few examples illustrate, there are many opportunities for dangerous leaks, explosions, or fires on campus if safety protocol isn't followed. Many schools find the gases are not properly stored, which leaves everyone on campus in danger. A recent safety bulletin from the University of Rochester found that liquid nitrogen was stored without an oxygen sensor, poisonous gas was used with a fume hood that did not adequately vent hazardous fumes, gas cylinders were modified using unacceptable materials, and gas tanks were stored without protective chains, stands, and gas caps. 

Why Schools and Universities Need an O₂ Monitor 

As the incident in the Hawaiian university lab illustrates clearly, compressed gases pose significant health risks in the university setting. Whenever safety protocol is not followed, the tanks are at greater risk of tipping, falling over, or leaking. 

While the lab worker escaped with her life, many others have not been so lucky. A nitrogen (N₂) gas leak causes death via asphyxiation in a matter of minutes. 

Nitrogen gas is both odorless and colorless. If gas leaks from a canister, there is no way for passerby to tell. As the gas leaks, it lowers ambient oxygen levels below safe thresholds. When levels of oxygen in the air fall below 16 percent, people can experience adverse health affects. Additionally, university property can be damaged by fires or explosions. 

All it takes it a couple of breaths of oxygen-deficient air for symptoms including confusion, dizziness, fatigue, muscular aches, lack of consciousness, and even death. 

Given the clear dangers that these gases pose, universities and schools must take steps to protect their students and staff. Fortunately, there is an easy and cost-effective way to detect gas leaks and alert everyone before oxygen is depleted from the air: Installing an O₂ monitor. 

An O₂ monitor, also called an O₂ deficiency monitor, measures levels of oxygen in the air all the time. As long as the air has adequate oxygen, the monitor will stay silent. When levels fall below safe thresholds, the oxygen deficiency monitor will flash lights and sound an alarm. This way, everyone in the vicinity of the leak can escape without suffering adverse health effects. 

An O₂ deficiency monitor should be installed anywhere that these gases are used or stored. Universities and schools may wish to equip labs, storage facilities, equipment rooms, and hallways or corridors that connect storage rooms with labs or classrooms where the gas is used. 

PureAire offers robust oxygen deficiency monitors that feature best in class construction. Made with zirconium oxide sensors, these monitors offer 10 or more years of maintenance-free performance once installed. These monitors can detect leaks of gases including argon, nitrogen, and helium. View PureAire's line of oxygen deficiency monitors at www.pureairemonitoring.com.

Are You An OLED Display Manufacturer? Why PureAire Monitoring Systems May Be Your Next Partner

OLED -- organic LED -- is a top desired feature in smartphones, yet manufacturers do not have the production capacity needed to meet industry demands. Since OLED devices have stronger contrast, a faster response time, a better quality, and a lower cost, there are many reasons for consumers as well as manufacturers to embrace this trend. To build capacity needed to product OLED screens for smartphones without sacrificing employee safety, semiconductor plants need two devices: An oxygen analyzer and an oxygen monitor. 

OLED Manufacturing and its Risks 

A good display is one of the strongest motivators to purchase a device, such as a television or a smartphone. The superior quality the OLED devices deliver will be a major driver for consumers, if these screens can make it onto a wide array of device types.

Next-generation OLED screens can even curve or roll up, like a newspaper. Kateeva is a company worth noting, as they are advancing OLED displays with over 200 million raised since 2008, using their YIELDjet FLEX printing tools. Two years after its debut, Kateeva’s YIELDjet FLEX tool is the undisputed leader in the industry. Kateeva’s President & COO was named “Inventor of the Year” for 2016 by the Silicon Valley Intellectual Property Law Association.

At present, only a handful of smartphone screens come with an organic LED. Apple hopes to ship all iPhones with OLEDs by 2018, but some doubt that facilities will have enough production to meet demands. At present, there is only one producer, Samsung, who is on board to provide the OLED screens. 

Efficient OLEDs are made using either an inkjet printing process or a process known as organic vapor phase deposition (OVPD). In the OVPD process, an inert gas (usually nitrogen or N₂) is used as a "carrier gas" to transport the organics onto a substrate, where they can condense. Nitrogen is a popular choice because it is inexpensive, efficient, and reliable.

Nitrogen can be generated on-demand using a generator that distils air into its component parts. An oxygen analyzer can help ensure the purity of the nitrogen gas created by measuring trace amounts of oxygen in ppm. By using nitrogen as the carrier gas, manufacturers can reduce the cost associated with making OLED screens and decrease the time to production.

How an Oxygen Deficiency Monitor Protects OLED Employee Safety

Inert gases including N₂ do not react with other substances. If the N₂ used as a carrier gas were to seep out from the generator or from supply lines, it would start to deplete oxygen present in the atmosphere. Since nitrogen gas has no odor or color, staff would be unable to tell that a leak had occurred without something like an oxygen deficient monitor in place. 

Within minutes of a leak, room oxygen levels would fall to below the minimum acceptable levels for oxygen. When this happens, anyone in the room would begin to experience respiratory symptoms, including mental confusion, loss of consciousness, and asphyxiation due to lack of oxygen. Accidents involving oxygen depletion are usually fast, serious, and frequently fatal. 

An oxygen monitor is a low-cost, effective way to monitor levels of oxygen anywhere that inert gases such as nitrogen are used. A wall-mounted oxygen monitor tracks oxygen levels on a continual basis and sounds a loud alert should oxygen fall below the 19.5 percent oxygen threshold earmarked by OSHA, a threshold that provides employees ample time to evacuate before succumbing to symptoms of oxygen deficiency.
By installing an oxygen deficiency monitor anywhere nitrogen gases are used or nitrogen generators exist, manufacturers can safeguard their staff while taking advantage of efficiencies that allow cheaper manufacturing of OLEDs. 

PureAire offers an oxygen deficiency monitors with a zirconium sensor, which is capable of withstanding 10 years of continued use. Because these sensors are long-lasting, they offer a good value compared to other types of sensors on the market. By installing an oxygen monitor to safeguard staff and an oxygen analyzer to protect the purity of the nitrogen gas, manufacturers can build capacity needed to meet the demand for OLED screens.   


PureAire's sensors are reliable, effective, and easy to set up. Once installed, they require no calibration to work. These monitors work in temperature extremes and remain reliable even when adverse weather affects barometric pressure. Learn more about oxygen monitors and analyzers from PureAire at www.pureairemonitoring.com. 

Air Separation Plants and the Use of Oxygen Monitors

Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is an important part of operational safety. Learn about air separation plant operation and safety protocol to be informed. 

How Air Separation Plants Work

In the cryogenic air separation process, air is chilled to the liquid stage. At this point, nitrogen and oxygen can be separated out from the inert gases in the air. Each compound can then be distilled at boiling temperature, thereby returning the liquid to a vapor state. The resulting nitrogen and oxygen gases are highly pure. 
To get the air ready to be separated, plant employees first filter the air to remove particles, such as dust. Next, the air is pressurized and then filtered up to several times to remove carbon dioxide, which can freeze the distilling equipment. 

Using a still and heat exchanger, workers heat and cool the gas, turning it into a highly pure liquid. The oxygen liquefies and falls to the bottom, while the highly pure nitrogen gas floats above the oxygen since it is lighter. 
Once separated, the gases can be kept in gaseous state or returned to a liquid state via chilling. Many air separation plants have elaborate pipe systems, whereby the oxygen or nitrogen gas can be transported directly to production lines. 

Air separation plants have many diverse uses. Pure oxygen gas is a basic component of metalwork including steel manufacturing. Nitrogen gas helps preserve edible oils from oxidizing and is used as a safeguard against combustion in shipping and cargo transit. 

The cryogenic process is effective and efficient at separating air; however, it does pose some safety risks. Air is safe to breathe when nitrogen and oxygen are together in the appropriate ratio. As nitrogen and oxygen are separated two distinct hazards emerge. 

Pure oxygen increases the fire danger in an environment. If not controlled, this could turn dangerous. 
Pure nitrogen depletes oxygen and can cause death via asphyxiation. Since nitrogen is colorless and odorless, workers may not know if the distilled nitrogen has escaped the still and infiltrated the environment. Argon acts in a similar manner, yet is a less common hazard since it is present in trace levels in oxygen. 
Without a safeguard of an oxygen monitor, staff may be exposed to toxic gases. In a worst-case scenario, staff could die. 

How an Oxygen Monitor Protects Staff

Between 1992 and 2002, 80 workers died from nitrogen exposure. Workers may fall unconscious after even a single breath of oxygen deficient air. If individuals do not receive oxygen in a matter of minutes, the consequences are grave. 

Educating staff about the dangers of these gases is a first step toward operational safety. Installing an oxygen or O₂ monitor is the next step to keeping everyone safe. 

An O₂ monitor measures the levels of oxygen in the air at any given time. The device takes sample readings of the air and remains silent as long as there is sufficient oxygen in the environment. Since argon and nitrogen deplete oxygen, the level of oxygen in the room will decrease if a gas leak occurs. When oxygen levels fall below the minimum safety level, the O₂ detector will sound an alarm. Trained staff will then know to evacuate the premises until emergency assistance arrives. 

Oxygen deficiency monitors from PureAire are guaranteed to perform for 10 years. These oxygen deficiency monitors have a zirconium oxide sensor, which accurately measures air oxygen levels in temperatures as low as -40 Celsius. The O2 monitor from PureAire is an efficient, cost-effective way for plants using nitrogen, helium, or argon to keep staff safe from the known health hazards of these gases.

CO2 Monitor For Breweries: Carbon Dioxide Safety and How to Stay Safe

Carbon dioxide is a necessary byproduct of the brewing process, yet too much CO2 can be dangerous to employee health. In Germany, two workers died at the same brewery in 2012 due to hazardous levels of CO2 present in beer mixing and pressure tanks. Learn more about how CO2 levels can get out of control during the beer brewing process and ways to protect your staff from this deadly gas.

Carbon Dioxide in Brewing

As beer ferments in stainless steel fermentation tanks, the yeast that was pitched into the wort eats up the natural sugars (glucose) over the course of 14 days or more. Lagers have a longer fermentation period of up to 6 weeks. During this time, the beer is held in a pressurized tank and kept at a constant temperature. As the yeast consumes the sugars, it creates carbon dioxide gas and ethyl alcohol. The alcohol-free wort then becomes both carbonated and alcoholic, essentially turning into beer as we know it.

Some carbon dioxide gas escapes the fermenter through an airlock during the initial fermentation period. However, as the beer finishes fermentation and reaches its final specific gravity (a measure of alcohol by volume), the airlock is capped and CO2 is then allowed to build up inside the tank. This ensures that beer becomes carbonated and develops the fizzy mouth feel you've come to associate with beer. Additional carbon dioxide can be added to the beer as needed to control the end result and ensure consistency in commercial brewing.

Hazards of Carbon Dioxide

While carbon dioxide is crucial to the taste and feel of beer, it is also highly dangerous. CO2 displaces oxygen, which can lead to asphyxiation if the oxygen deficiency is not corrected. CO2 can also be highly toxic, even at levels as low as 0.5%. Exposure to more than 10% by volume of carbon dioxide can cause death within minutes. By the time a fellow staff member realizes that a colleague is non-responsive or has been overcome by exposure, the damage is done.

Brewers must control their exposure to CO2 through all aspects of the beer brewing process, from fermentation to packaging and bottling. CO2 is heavier than air, so it will settle to the bottom of fermentation tanks. The gas can then escape from fermentation tanks and hide on the brewery floor, in invisible and dangerous pockets of air.

Since carbon dioxide gas is odorless and colorless, brewery workers may not know when they are being exposed to dangerous levels of CO2 until it's too late. Even if staff are trained in the best practices regarding carbon dioxide in the environment, they cannot protect themselves from something they cannot see or smell.

To keep staff safe, it's a smart idea to monitor levels of carbon dioxide in the air. A dual-use oxygen/carbon dioxide sensor can monitor existing levels of CO2 and alert staff if the amount of CO2 start to rise. This monitor can also track the level of oxygen, sounding an alarm if oxygen levels fall to a point where staff do not have enough oxygen to breathe.

When levels of CO2 reach the point that can be hazardous to health or exceed the minimum exposure risk, or when the amount of oxygen in the air becomes too low, visual and auditory alarms go of that alert all staff on the brewery floor to the dangers. Staff can then evacuate the premises safely.

These monitors take readings of the levels of O2 and CO2 in the environment at all times. If levels become too high, brewery staff can remove carbon dioxide from the environment by using the ring main or manually removing the CO2.

PureAire offers a dual O2/CO2 monitor that has a zirconium sensor, which is uniquely equipped to perform in humid environments where temperatures fluctuate. The same Co2 detector can last for up to 10 years, and will not require significant maintenance or calibration to remain accurate. Compared to other brewery CO2 monitor offerings, PureAire's are accurate, durable, reliable, and easy to use.
As a leading expert in the area of carbon dioxide monitoring, PureAire has more than 15 years of experience creating durable oxygen deficiency monitors.

Cryotherapy is Cool

Cryotherapy is a real facet of medical treatment that uses extremely low temperatures to help with pain and inflammation. Not to be confused with cryopreservation, in cryotherapy the patients are only subjected to the cold for minutes. It seems like something futuristic, but it is actually an increasingly common treatment among athletes to replace ice baths and ice pack therapies.

More specifically, cryogenic chamber therapy, or Whole Body Cryotherapy (WBC), uses liquid nitrogen to cool a chamber to around -185oF. The patient spends a few minutes in the chamber wearing only a bathing suit, socks, gloves and facial protection (to prevent frostbite), allowing the skin temperature to drop while the core body temperature remains stable. This WBC treatment improves many types of muscle and joint pain and helps in the rehabilitation of injuries.

These cryotherapy systems are currently being used by sports teams such as the San Antonio Spurs, the LA Clippers, and the Minnesota Timberwolves, just to name a few. Everyone from Olympians, to rugby players, to non-athletes looking for pain relief utilize WBC. The super cooling power of liquid nitrogen can be a blessing to those in pain, but precautions need to be taken to assure this tricky chemical remains safe. In the event of a liquid nitrogen leak, the patient could suffocate from lack of breathable air. This is why an Oxygen Deficiency Monitor is important to have in any facility that uses liquid nitrogen.

PureAire Monitoring Systems provides a product that would be ideal for this type of application. Their Oxygen Deficiency Monitor that uses a sample draw system is one of the best in the industry, and can be hooked into an alarm or horn and strobe to alert the chamber operator and patients in case of a leak. The oxygen monitor can even be programmed to turn off the nitrogen tanks in the event of a leak in the system.

The O2 monitor would be situated outside the chamber. Through a tube, air samples from inside the chamber would be analyzed to make sure the oxygen level remains at a safe and breathable 20.9%. Any nitrogen leak would reduce the percent of oxygen and trigger an alarm. Because the oxygen deficiency monitor’s sensor lasts at least 10 years without maintenance, safety is guaranteed for many years to come. Cryogenic chamber therapy has the potential to help many people treat their pain, and with the use of an oxygen monitor, they can do so safely.

PureAire’s O2 Monitor used in High Altitude Training Gains Recognition among Athletes

Since 2006 PureAire Monitoring Systems O2 Monitors have been used in Hypoxic High Altitude Training rooms. The training rooms are designed to lower the breathable oxygen using nitrogen, and the oxygen monitor is needed to maintain the environment. The technology used to lower the O2 level is used with a nitrogen generator. By lowering the breathable oxygen this creates a more strenuous workout for an athlete. The generator is important as it dispenses on demand nitrogen at any given time lowering the oxygen levels. For typical training, the oxygen levels are near 15% with the balance of nitrogen. At 15% oxygen the altitude system tricks the body to believe it is training around 8,000 ft above sea level. The O2 deficiency monitor operation range is 0-25%. PureAire’s O2 deficiency monitor was defined as the best product to maintain these stable oxygen levels. Hypoxico Altitude Training Systems is the first to start selling and marketing a product like this. PureAire’s oxygen deficiency monitor uses a zirconium oxide sensor. The monitor does not require maintenance or calibration. For these reasons, PureAire has been specified as the best fit for the altitude systems. The sensors life expectancy is 10+ years. In addition, the sensors are completely linear full scale of 0-25% giving an almost analyzer quality for the athletes. Some clients which have been reported to use these altitude training systems are Prince Harry, Lance Armstrong, David Beckham, Cleveland Indians, Bear Grylls, and Michael Phelps. On 60 minutes Michael Phelps talks about using an altitude tent, but said he did not want to show this room to cameras. Many other athletes use altitude training as part of their exercise routines as well. Altitude is characterized by the reduced partial pressure of oxygen. At a lower partial pressure, there is less oxygen in the air you breathe. It is this reduced oxygen content that stimulates the body to adapt and become more efficient in the uptake, transportation, and metabolism of oxygen. The HYPOXIC ALTITUDE TENT utilizes the same oxygen reduced air that one would find at high elevations. Our Hypoxic Generator continually separates out a portion of oxygen from ambient air before it is pumped into the enclosure. All other gases remain in the air, maintaining the atmospheric pressures of sea-level (or whatever altitude you are living at)1 The main O2 Monitor function which controls the desired training elevation, in the altitude room, is called hysteresis. Hysteresis is similar to how an air conditioner keeps a desired temperature range in one’s home. For example, if 70f degrees are set on a home’s air conditioner, when the temperature begins to rise to 71f, the temperature control (hysteresis) turns on the air conditioning lowering the temp back down to 70f. The PureAire O2 monitor has the same function. If the altitude room requires 15% oxygen, PureAire’s O2 monitors hysteresis will work similar to the air conditioner in a home. When the O2 levels rise to 15.5%, the O2 monitor will control the nitrogen generator lowering the O2 to the desired range of 15%. PureAire is the only O2 monitor being used for altitude training systems currently and with the growing amount of athletes training, PureAire believes only the demand for these training systems will go up in the future.

Is your company using Nitrogen or other Cryogenic gases? Why PureAire Recommends an O2 Deficiency Monitor for Safety.

PureAire Monitoring Systems, Inc. focuses solely on safety in the workplace, and in laboratory environments. Oxygen deficiency monitors are used in areas using Nitrogen, Helium, Argon, and Carbon Dioxide. PureAire strongly recommends an oxygen deficiency monitor to be installed anywhere cryogenic gases are being stored. The purpose of an oxygen monitor is to alert employees in the immediate area if there is a spill of nitrogen with audible alarm. The use of an O2 monitor creates a safer environment for employees and can alert local fire panels in a building as well. In New York, NY any area using more than 50 gallons of nitrogen the law states, it is mandatory for an oxygen monitor to be installed. The largest problem with these specialty gases are, if a spill occurs there is no noticeable scent or effects. A nitrogen spill can create an oxygen deficient environment rapidly within seconds. For the time it takes the body to realize there is zero breathable oxygen, it is too late. A person will pass out from oxygen deprivation immediately. This is one of the most preventable incidents; simply install an oxygen deficiency monitor for safety. Consider an argument for medicine. If one was to travel to the Amazon in South America, where malaria is common, being unaccustomed to the jungle, wouldn’t it be wise to take malaria pills? What if you have a family history of diabetes? As a family member you may consider taking any necessary precautions to possibly eliminate the concern of diabetes. Maybe by being more physically active, or having a healthier diet, this may delay or stop the onset of diabetes. An oxygen monitor is also similar to a Fire detector in your home or office. You never expect to have a fire, but a fire detector is installed for safety as a precaution. PureAire feels the oxygen monitor is the preventative medicine. Scientists and researchers will always continue to use nitrogen for their experiments. Doctors will continue to use helium to cool the large magnets used for images in the MRI scanner. Carbon dioxide will still be used for all beverage dispensing systems at fast food chains. The one factor people cannot eliminate is the use of cryogenic gases used in everyday life. The only known safety, and scientifically proven device is the oxygen deficiency monitor. The rooms dimensions, a size of the cylinders, the quantity of the cylinders, the types of cryogenic gas being used, whether the gas is being piped into a room, and height of the ceiling all play a role on where, and how many monitors are required. PureAire often gets the question, where do we place the oxygen monitor? How many O2 monitors should we use? A few simple tips can help save a life. Helium is lighter than air, so it is recommended to mount the monitor closer to the ceiling, whereas nitrogen/argon is heavier than air, so mounting the monitor closer to the ground would make sense. Carbon dioxide is also heavier than air settling to the ground. PureAire manufactures oxygen deficiency monitors for many different areas. In all cases PureAire use an oxygen deficiency monitor using a 10+ year sensor. PureAire can be contacted at 1-888-788-8050, http://www.MonitorOxygen.com, and http://www.PureAireMonitoring.com.

The Beverage Industries Incorrect Way of Monitoring for CO2 leaks: Why CO2 Monitor is the Wrong Solution. Hear why PureAire’s Oxygen Monitor is a Bett

Carbon Dioxide (CO2) is the primary compressed gas used for beverages at major fast food chains. This gas is also used in restaurants, gas stations, and grocery stores. When CO2 leaks into a confined space or basement, this creates a very unsafe workplace for employees by lowering the breathable oxygen. History seems to repeat itself all too often while dealing with CO2. Due to the CO2 leaks several times a year, employees have become sick and in worst cast scenarios, have died from asphyxiation.

Below is a link to the Phoenix Fire Department video on a CO2 leak at a fast food chain. Two Fire men were overcome by CO2 in a basement of a chain. http://nfpa.typepad.com/fireservicetoday/2011/10/lesson-learned-co2-leak-at-mcdonalds-harmful-to-employee-and-responders.html

It has become a standard in the industry to use a CO2 monitor; this is outdated and should be replaced with an Oxygen Monitor. CO2 Leaks are a Oxygen deficiency problem as CO2 displaces oxygen creating an unsafe workplace. PureAire is a leader for oxygen monitors in the workplace for safety. PureAire makes an Oxygen monitor with a 10+ year sensor without maintenance, and calibration. This is very important advantage over the CO2 monitors being used.

The CO2 monitors installed in fast food chains are the wrong approach. The CO2 monitors used are low cost, and can do more harm than good. A gas monitor is a scientific piece of equipment. The technology used in the CO2 monitor requires maintenance, calibration, and monthly testing. Without oversight, the monitors will begin to fail or become unresponsive. The lacks of attention to the current CO2 Monitors are a common problem amongst the fast food employees.

Employees at fast food chains are not trained on compressed CO2 typically. Employees are the first people to work with CO2, and in most cases are required to change CO2 gas in a basement or confined space. What if there is a leak? What if the CO2 monitor is non functional? This result can be catastrophic.

PureAire believes strongly the answer is not a CO2 monitor, but an Oxygen Monitor. CO2 will always displace oxygen and will lower the breathable oxygen levels. PureAire’s Oxygen Monitor is unlike any other, using a 10 + year sensor which is 24/7 supervised. The O2 Monitor is safer and much more reliable. Using PureAire’s O2 Monitor will eliminate the concerns about CO2 spills. If there is a leak of Oxygen, the O2 Monitors alarm will sound alerting employees. PureAire‘s 24/7 supervision will ensure the monitor is functioning properly, and responsive when it is needed most.

PureAire’s knows you cannot always count on an employee’s knowledge of the CO2 risks, the signs of CO2 exposure, and the dangers of CO2. This is why PureAire’s monitor is the best choice. The monitor can also be configured with an exhaust fan, further enhancing the safety with complete automation.

Why the use of a CO2 monitor may not be the best solution for protecting workers against leaks from beverage dispensing systems in the fast food ind

Carbon Dioxide (CO2) is the primary compressed gas used forhttp://www.blogger.com/img/blank.gif dispensing beverages at fast food chains. This gas is also used in restaurants, gas stations, and grocery stores. When CO2 leaks into a confined space or basement, it creates a very unsafe environment for employees because it lowers the concentration of breathable oxygen. History seems to repeat itself all too often while dealing with CO2 leaks from dispensing systems. Due to numerous CO2 leaks in the workplace, lower oxygen levels have resulted in employees becoming sick or dying, from asphyxiation.

Below is a link to the Phoenix Fire Department video on a CO2 leak at a fast food chain. An employee and two firemen were overcome by a lack of oxygen due to a CO2 leak in the basement of a restaurant. http://nfpa.typepad.com/fireservicetoday/2011/10/lesson-learned-co2-leak-at-mcdonalds-harmful-to-employee-and-responders.html

The use of a CO2 monitor is accepted as a standard method in the industry, however since a leak actually creates an oxygen deficient environment; the use of an Oxygen monitor would provide better protection. CO2 displaces oxygen.

PureAire is a leading supplier of oxygen monitors for protecting people in the workplace. Its Oxygen monitor uses a proprietary non depleting sensor with a 10+ year life. The monitor requires no maintenance or the need for routine calibration; a very important advantage over the CO2 monitors being used.

The use of a CO2 monitor to protect people against oxygen deficiency in fast food chains can be the wrong approach since it’s the lack of breathable oxygen that is causing injury. Companies however are attracted to the low cost of CO2 monitors and since there is no regulation to use oxygen monitors, there is no incentive to provide better protection. Virtually every response to a CO2 leak resulted in a conclusion that workers were overcome by a lack of oxygen, which cannot be detected using a CO2 monitor.

PureAire believes that the use of a CO2 monitor alone cannot provide adequate protection to a leak. When storing large cylinders of liquid CO2 in confined spaces, complete protection should include an oxygen deficiency monitor.

Most users of CO2 dispensing systems do not have trained technical staff to maintain a monitoring system. All monitoring and system functions on PureAire’s oxygen monitor are 100% supervised and fault protected. Employees are always assured of continuous protection and are alerted to any failures.

The earth is a wonder source of calibrated oxygen and under normal ambient conditions of 20.9%, the monitor is continuously exposed to calibrated gas. CO2 monitors read zero when not exposed, and therefore require routine calibration to insure they’re working. This is not required for PureAire’s oxygen monitor.

In addition to its long life, no maintenance sensor, the oxygen monitor has built-in alarm relays for controlling ventilation fans or connecting to standard fire alarm panels. A major producer of CO2 gas actually uses PureAire oxygen monitors in their gas processing plant because of their concern of lower oxygen levels due to a CO2 release. We agree with them.

PureAire Monitoring Systems Grows their Sales Once Again

In the past year PureAire Monitoring Systems has grown at the rate of 50%. PureAire is known for the manufacturing and selling of safety gas monitors. There monitors are used in environments such as laboratories, pharmaceutical industries, medical laboratories, universities, nitrogen manufacturing plants, cold storage warehouses, and other various areas where air conditions can be at risk PureAire started in 1997 and has continued to develop new gas monitors for safety in the workplace. They are continuing to push the envelope of technology with the help of well esteemed engineers, and president.

One monitor that has helped attribute to PureAire’s sales is their Oxygen Monitor. Known as the Aircheck TX-1100-DRA, this monitor uses a 10+ year sensor technology which has left their competitors in the dust. Being sold since the 1970’s by their affiliate company Bionics, PureAire re-engineered the monitor and complimented the sensor technology, ultimately increasing the accuracy and stability. The newly developed 3.05 revision software update has even outperformed their previous tests. In addition to their newly designed software, there is a built in horn/strobe, LCD backlight digital display, 2 user selectable alarms, and a 4-20 mA signal for control panels. There hassle free Oxygen Monitor is being used at the most prestigious Universities such as Harvard, UCSB, UC Berkeley, and Cornell.

In addition to, a more recent sought out monitor has been their Methyl Bromide Monitor for fumigation. A monitor being sold for many years, also received an update in their software and hardware. Since 2008, PureAire received a EPA, DPR, and USDA compliancy for their safety methyl bromide monitor in the workplace. PureAire is the only company that makes a 24/7 supervised Ch3Br monitor used to measure in the ppm. Repeatable and reliable tests prove the monitor can be used to measure less than 1ppm. Low.4ppm or 400 ppb can be measured in areas containing methyl bromide gas. Before PureAire’s monitor, sampling tubes (Draeger or Kitagawa Colorimetric Tubes) were the only option to take a real time sample. To measure an air sample, an employee would need to take it him/herself. This ultimately brought up a safety concern for the employees, especially if there is a high concentration of methyl bromide in the area.

Primary areas where PureAire’s methyl bromide monitors are be sold are in cold storage facilities housing pre-fumigated produce before distribution throughout the country. For example, grapes are being shipped abroad to US ports. Before they are distributed to local grocery stores they are fumigated with Ch3Br in high concentrations eliminating pests, etc. Fumigation also ensures the produce is safer before being sold to consumers. The monitors are also used for the residual fumigation of walnuts, asparagus, avocados, apples, and strawberries

Also, PureAire is working on a multi point methyl bromide monitor which is in pre-production stages, hoping to be released to the public in the first quarter for 2012. This will be a 4 channel monitor for clients interested in monitoring 4 separate areas. As PureAire continues to grow, so will the development of newer and edgier products.

PureAire’s Oxygen Monitor uses a 10 + Zirconium Oxide O2 Sensor: Unlike the 1000 C degree Stack O2 sensors.

PureAire makes an Oxygen monitor for laboratories where nitrogen, helium, argon, carbon dioxide, and any cryogenic gases are stored. The O2 monitors are a standalone wall mounted unit with a built in audible alarm. The monitor utilizes a 10 + year Zirconium Oxide (ZrO2) sensor and has a backlit digital display showing readings of 0-25% range. PureAire has sold there O2 monitors while combining a ZrO2 sensor since the company started in 1997, and has contributed to their growth of 50% in 2011.

There are two types of ZrO2 sensors: There is a high temperature sensor (1000 C) for stack Oxygen monitoring, and a low temperature sensor PureAire uses. PureAire uses an Oxygen sensor that has a operational temperature near 400 C. Though this seems hot, the zirconium oxide sensor is quite stable and long lasting at this temperature.

The ZrO2 sensors (1000 C) commonly used for Stack O2 readings only have a life expectancy of 2-3 years. The contributing factor is the high temperatures achieved to gain there readings. PureAire utilizes a similar technology, but due to the lower (400 C) operational temperatures PureAire can increase their life expectancy to 10 years and more.

The ZrO2 oxygen sensor is very similar to the O2 sensors in automobiles for combustion. Every car has a O2 sensor and due to the long life expectancies, this is why automobile manufactures use them.

PureAire continues to strive for perfection. To maximize the most from their oxygen monitors, many years of R&D had to take place. The driving force behind developing the best oxygen monitor was the vision of making a monitor that would last for many years, and be easy for the consumer. Besides their main selling point of having a no maintenance O2 monitor, they have given the user a joystick for maneuvering through the menus. It is responsive while working through the menus, and easy to adjust simple functions such as alarm set points.

The researchers at PureAire wanted to make it a point that nobody should confuse the two technologies of zirconium oxide sensors. While PureAire’s O2 sensor does seemingly have a high operational temperature, all automobiles use a similar technology and nobody seems to think twice about them.

PureAire has been trying to educate people about this technology for years, and companies are starting to recognize them as an industrial O2 monitor leader.

While there are more than 2,000 PureAire oxygen monitors are in the field, people are still becoming aware every day. PureAire’s goal is to be the leading manufacture O2 monitors for 0-25% and if 2011’s growth has anything to show for it, I think they will.

PureAire Makes Oxygen Monitor for Nitrogen Generators

Nitrogen generators are most commonly used in areas where on-demand nitrogen is preferred rather than, storing liquid nitrogen (LN2) in cylinders. Nitrogen generators have a lower cost of operation, and can be used where smaller amounts of nitrogen are needed. Nitrogen generators are used in the pharmaceutical industry, testing laboratories, cryogenic facilities, welding manufactures, and petrochemical environments.

The question often comes up from a safety standpoint, is nitrogen a safe? The answer is usually no. An Oxygen Monitor is needed where LN2 or nitrogen generators are stored. Nitrogen makes up roughly 70% of the air we breathe, though oxygen is only 20.9%. Oxygen is a precious gas that we take for granted. Ultra pure 99.9% nitrogen is unsafe in confined spaces, and nitrogen generators are usually stored in these types of areas. PureAire has developed an Oxygen Monitor with a 10+ year sensor made specifically for nitrogen storage areas, and nitrogen generators.

PureAire’s O2 Monitor uses a called Zirconium Oxide sensor. Most Oxygen Monitors use a disposable electrochemical sensor that typically only has a life expectancy of 12-18 months along with other complications. Some examples of problems with the electrochemical sensors are: drifts to thunderstorms, or barometric pressure changes, humidity changes, and temperature fluctuations.

PureAire has pioneered the way using a zirconium oxide oxygen sensor. The technology used is far more advanced than the “Old style,” electrochemical sensors. The sensor used is based on ions being passed through the sensor, and at 20.9% oxygen a certain quantity of ions cross the sensor. Thus, giving a current to the monitor giving an accurate reading between 0-25%. If the oxygen concentration has been lowered, fewer ions cross the sensor hence, lowering the reading on their display. Intuitively, if there is higher known concentration of oxygen, so will the sensors readings on the PureAire Oxygen monitor.

The crucial understanding of the sensor is what gives PureAire’s clients the 10+ life expectancy and accuracy. Another great property of the ZrO2 sensor is NO CALIBRATION is required. The sensors ion technology limits the need to calibrate. PureAire’s Oxygen monitor does not have problems with barometric pressure, temperature, or humidity changes. PureAire’s O2 Monitors are completely stable (-40c to 50c) in all environments.

Nitrogen generators create high pressure in the cylinder after the gas has been created. This can be dangerous especially, overnight while employees are not in the proximity. PureAire also has a feature called latching. If there is a leak overnight, the alarm can stay alerted until the client turns off the switch in the morning.

PureAire is also looking for distributors to help distribute their oxygen monitors. In the past year PureAire has grown 50% and is continuing to gain more recognition. The demand for the O2 monitors has been more abundant exponentially. The PureAire ion based technology O2 monitor should be the only monitors being sold for 0-25% due to the lack of maintenance and calibration.

PureAire’s Oxygen Monitor for Liquid Nitrogen Storage uses a 10+ Year sensor.

PureAire Monitoring Systems manufactures a variety of safety gas monitors, including the top selling oxygen monitor. PureAire’s oxygen monitors are used in areas containing liquid nitrogen, bulk nitrogen, or nitrogen Dewar storage. Recently, there has been a heightened awareness of nitrogen dangers in confined spaces, and ultimately an increased demand for fixed oxygen monitors. For years oxygen monitors have been used in confined spaces, but portable monitors were primarily used. Fire marshal’s, EH&S officers, and safety departments are now requiring companies to use oxygen monitors in almost all areas containing nitrogen tanks.

Typical facilities using LN2 (liquid nitrogen) are nitrogen manufacturers laboratories, semiconductor, cleanrooms, cryogenic freezers, food industries, NMR (nuclear Magnetic resonance) suites, cryopreservation, and confined spaces. Recently, PureAire has been working with companies like Praxair, Air Liquide, Air Gas, and Air products to help distribute to their clients. They believe PureAire has an alternative that is unlike anything else they have seen in the industry.

PureAire’s oxygen monitor uses a unique ZrO2 sensor with a 10+ year life expectancy. Also, more importantly the sensor is linear from 0-25%. If a client’s criterion requires seeing 15% oxygen, PureAire’s oxygen monitor will be accurate within .1%. The proprietary electronics is the backbone of the oxygen monitor. Other ZrO2 oxygen monitors exist though can only see an accurate reading at 20.9% due to lack of its electronics package.

Numerous tests have showed PureAire’s oxygen monitors readings are comparable to very expensive Oxygen monitor analyzers in the percent range. Though not marketed as an analyzer, if the client needs a cost competitive real-time monitor in the percent, nobody can match the precision PureAire’s oxygen monitor offers. Analyzers are accurate and dependable but are known for their constant calibration, and lack of real time monitoring.

PureAire requires no calibration, no replacement sensors, no maintenance, and no drifting to thunderstorms (change in barometric pressure).

Important questions to ask when purchasing a oxygen monitor? (This does not apply to PureAire)

1. How often do you calibrate a sensor?
2. How often do you replace a sensor?
3. How much does a sensor cost?
4. How long is the wait time to get a replacement sensor?
5. What is the shelf life of a sensor?
6. What happens if you do not calibrate a sensor?
7. What is the accuracy of the monitor?

Answer: Use a PureAire monitor.

PureAire Receives CE Approval on its Oxygen Monitor with 10+ Year Sensor.

PureAire Monitoring systems, the proud manufacture of their oxygen monitor has received a CE approval. The recent CE approval is monumental for PureAire selling to European countries. PureAire has been selling their O2 monitors in the USA for over 11 years. With a larger demand from their clients it was certain a CE approval would be beneficial to their product line, especially in Europe. PureAire’s oxygen monitor is highly revered for its 10+ year sensor requiring no replacement sensors, calibration, or maintenance.

When PureAire’s VP of Sales, Brandon Alan was asked, why is your O2 monitor different? Brandon explained the background of oxygen monitors; he discusses there is a lengthy maintenance process required to have a properly functioning monitor, until we, PureAire came out with the Aircheck Oxygen Monitor.

Brandon States, “About 95% of all Oxygen Monitor manufacturers use a continuous depleting sensor for O2 their readings. Clients will replace sensors on average from 12-18 months at $250 per sensor, and requires quarterly calibrations if their lucky. We have overcome the burden for our clients, and have provided an O2 monitor that is ultimately hassle free by using the zirconium oxide sensor. Gaining recognition of PureAire’s oxygen monitors has been an uphill battle, but companies are catching on quickly.”

So, where might you find Oxygen monitors being used?

Brandon: “Oxygen monitors are used in areas where the client may be worried for their safety due to a potential low oxygen level. More recently MRI rooms have been a risk due to the helium storage in the large magnet MRI scanners. Most people are not aware of the risks associated with helium. Most people joke if there was a leak of helium, they would talk like Mickey Mouse. Though, I do find humor in high talking Walt Disney characters, this can be a very serious matter. Our typical oxygen monitor client uses liquid nitrogen cylinders, nitrogen dewars combined with confined spaces, and laboratories containing cryogenics. The three largest Cryogenic gases (Oxygen depleting gases) are Nitrogen (N2), Argon (Ar), Helium (He), and Carbon dioxide (CO2).”

How do you see the CE approval helping your oxygen monitors sales?

Brandon: “I anticipate once the message gets out that we have a CE approval, European companies will start to take notice of our monitors. We understand in order to sell our products to other European countries we must have an approval. I am hoping companies will use our oxygen monitors based on our technology. Were hoping the old throw away sensor technology becomes an idea of the past in Europe, and our O2 monitor with 10+ year sensor becomes the product for the future.”

Oxygen (O2) Monitor for MRI Rooms: PureAire Sells a Hassle Free 10+ Year Oxygen Monitor.

Magnetic Resonance Imaging (MRI) facilities have the same thing in common, helium. Helium is used as part of the cooling process for a MRI magnet. PureAire Monitoring Systems Oxygen Monitors are becoming the newest safety product amongst MRI users, thanks to its 10 + year sensor. PureAire’s sensors do not require maintenance, or require replacement parts. Helium is a nontoxic, odorless, colorless, nonflammable gas stored in cylinders at high pressure. It can cause rapid suffocation when concentrations are sufficient to reduce oxygen levels below 19.5%. It is lighter than air and may collect in high points or along ceilings. Self-Contained Breathing Apparatus (SCBA) may be required by rescue workers1.

The above statement is from a Air products MSDS sheet. In addition, ACGIH considers Helium a simple asphyxiant. PureAire has been in business for 14 years selling their highly revered O2 Monitors for safety in MRI facilities for physicians, clients.

“Thanks again for your support. The oxygen monitors are in their respective locations and are functioning as designed. Nice unit! Everyone thinks they are a great product. The software menu is easy to use and could not be easier to operate.” Dominion Nuclear.

Currently PureAire’s O2 Monitors are being used at MRI facilities around the world. O2 Monitors have been used for over 30 years, though most people are accustomed to using an O2 monitor with sensors only lasting 12-18 months. In addition to, they must be calibrated and maintained to function correctly. PureAire’s 10+ Year O2 Deficiency Monitor is much more reliable, requires no maintenance, and does not need to be calibrated. There zirconium sensor does not have the biases associated with the disposable sensor technology. This means no more false alarms and drifting, and an always-accurate reading.

When asked of MRI facilities, do you have an O2 monitor? There common response was I am not sure, or what is it? This was unfortunate in most cases, and when we presented our O2 monitors technology and made them aware. There perspective was significantly different and wondered how to best attain one.

Increased Demand for PureAire’s Oxygen Monitor for Nitrogen and Helium Storage

When storing or using Liquid Nitrogen, Helium, CO2, or Argon cylinders in a confined space, what are the potential risks? Gas leaks are the most common, requiring the need for an oxygen deficiency monitor for protecting employees in the workplace. With inert cryogenic gases, loose or broken fittings can leak gas into a room displacing oxygen, causing impaired judgment or loss of life to workers. PureAire, one of the leading suppliers of Oxygen Deficiency Monitors uses a non-depleting zirconium oxide sensor that has a 10+ year sensor life and requires no calibration or periodic maintenance.

“Cryogenics are mostly stored in confined spaces such as, offices, freezers, or hallways. One of the most overlooked additions to having LN2, He, Ar, or CO2 cylinders ranging from 25-250lbs is the O2 monitor. MSDS sheets all have a variation of information mentioning, high pressure and suffocation with No Odor1.” “In high concentrations, asphyxiation occurs with no warning. Symptoms may include loss of mobility/consciousness and must apply artificial respiration if breathing stopped2.”

The rapid release of nitrogen, and other various cryogenics possess absolutely zero signs of immediate danger. NIOSH, and OSHA states anything under 19.5% oxygen is considered hazardous, and a dangerous environment for employees. The earth is a wonderful source of calibrated oxygen and we breath 20.9% Oxygen. PureAire’s Oxygen detector is one of the most widely used real time monitors for detecting leaks among cryogenic gas cylinders in storage rooms. If a gas spill or leak occurs, PureAire’s Oxygen monitor is designed to turn on strobes and audible alarms to warn workers to evacuate the location. It also has built-in relays that can active ventilation fans to bring in fresh air.

PureAire’s Oxygen monitor uses a 10+ year zirconium sensor. The monitor requires zero maintenance, and calibration because of its non-depleting long life sensor. Built in “supervised watchdog” software continuously monitors all instrument functions 24-7. PureAire’s Oxygen monitor is not affected by humidity, temperature, or changes in barometric pressure. Rapidly changing barometric pressure changes from thunderstorms will not disrupt PureAire’s Oxygen Deficiency Monitor. The majority of oxygen deficiency monitors sold use depleting electrochemical sensors that need complete replacement frequently. PureAire’s Oxygen monitor can save up to $400 annually in replaceable sensors.

Oxygen (O2) Monitors: Disposable Sensors eating your Cash? PureAire Introduces 10 + Year Sensor.

PureAire Monitoring Systems is a leading manufacturer in the gas monitoring industry. When it comes to O2 deficiency monitors PureAire makes the most reliable, longest lasting, and affordable oxygen monitors.

It has been an international standard for the past three decades to use oxygen monitors with disposable sensor cells, (electrochemical sensors). All disposable sensors require frequent maintenance, monthly and quarterly calibration (false alarm if not calibrated), and usually drift to changes in barometric pressure. At PureAire, we made a point to fix this familiar problem and offer you a solution. We created a better product, one that eliminates the inconveniences of disposable sensors while continuing to meet your needs.

The 10+ Year O2 Deficiency Monitor is a unique product offered by PureAire. The Zirconium Oxide (ZrO2) sensor is the key technology that has allowed us to continue providing reliable and long lasting monitors over the years.

The ZrO2 sensor does not rely on partial pressure, or need a reference gas like disposable sensors. Also, our sensor does not require electrolyte, a depleting source of power, while disposable sensors require this fluid to give the sensor its power. Our sensor’s power comes from 24VDC, and does not have a depleting source. PureAire’s 10+ Year 02 Deficiency Monitor is much more reliable, requires no maintenance, and does not need to be calibrated. There zirconium sensor does not have the biases associated with the disposable sensor technology. This means no more false alarms and drifting, and an always-accurate reading.

With over 1,000 monitors in the field, PureAire continues to gain support amongst its users with a hassle free O2 monitor for safety. With our O2 Monitor you can be assured if there is a leak from any cryogenic gas (LN2, He, Ar, and CO2), our built-in audible will go off without any false alarms.
