The Air check O2 Deficiency Monitor is a compact gas monitoring system that's ideal for the continuous monitoring of inert gas storage areas, freezers, confined spaces, and other locations where low oxygen levels may pose a hazard to personnel. 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 heart of the monitoring system is a long lasting zirconium sensor, which responds to low oxygen conditions within seconds and provides accurate measurements over a wide temperature and humidity range. 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 polycarbonate housing or optional EX for hazardous areas.
