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.
