PureAire's O2 deficiency monitors are designed for labs containing liquid nitrogen, confined spaces, and MRI rooms requiring the need for a sample draw version. If there is a spill of oxygen depleting gases (N2, Ar, CO2, and He) our monitor will sound an audible alarm in seconds.

Our hassle-free O2 monitor uses a 10+ year sensor which requires no calibration or maintenance. There are no hidden costs with our monitors, and replacement parts or sensors required. Recently CE approved. Non sample draw and explosion proof versions are also available.

Unlike electrochemical sensor cells the Air check O2 zirconium cell provides stable oxygen readings even in areas where temperature, barometric pressure and humidity levels are changing. The PureAire Air check O2 Deficiency Monitor is suitable for either indoor or outdoor use. The zirconium O2 sensor cell will operate continuously for 10 or more years and requires an absolute minimum of maintenance. There are no zero or span calibration pots to adjust and when compared to disposable type sensors, our long life zirconium O2 sensor can save up to $475 annually and will pay for itself in just over 3 years! Ideal for continuously monitoring oxygen levels in confined spaces or areas where inert gases are used, the Air check O2 Deficiency Monitor does not drift or loose sensitivity when the weather or temperature changes. The electronics are housed in a Nema 4X housing or optional EX for hazardous areas.
