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.
