Oxygen Deficiency Monitors

The Oxygen Deficiency Monitor is a compact gas monitoring system that provides stable oxygen readings despite changing temperature, barometric pressure, and humidity levels. 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. There are no zero or span calibration pots to adjust and when compared to disposable type sensors. It can save up to $475 annually and will pay for itself in just over 3 years! The only optional response test required is to subject the O2 system to nitrogen periodically. Regulated 24VDC power supply is required.
