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.

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.
