Methyl Bromide Monitor EPA Compliant

The Air check Advantage Methyl Bromide Gas Monitor is a compact, extractive gas monitoring system that’s ideal for continuously and remotely monitoring gas cabinets, process tools, scrubber systems, and other areas where maintenance access may be limited or undesirable. Featuring a long life pyrolizer and sample pump, this reliable hazardous gas detection system significantly reduces the labor and downtime commonly associated with gas detector maintenance and service.

The instrument’s “smart” circuitry continuously monitors sensor cell status and sampling system performance. Continuous sensor cell operation is transmitted via 4-20 mA signal to PureAire controllers, PLC’s or remote alarm systems. Should a system error occur, the Air check Advantage outputs a 2 mA signal to remote alarm/control systems to immediately alert control room personnel.

The heart of the system is a smart renewable sensor cell linked to a compact pyrolizer. Sample is drawn through the pyrolizer where Methyl bromide is thermally decomposed and converted into another gas that is more easily detected electrochemically. Unlike competitive Methyl bromide detectors, which measure at the percent LEL levels, the Air check Advantage measures at the PPM OSHA TLV levels.

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.


“When it comes to safety, why not use something that’s going to last.” Brandon Alan. If you have anymore questions, please feel free to contact us at www.PureAireMonitoring.com, or www.MonitorOxygen.com.

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.
