Oxygen Deficiency Monitor for O2 Depletion Safety

The PureAire Oxygen 0-25% Deficiency Monitor is perfect for facilities that use inert gases such as nitrogen, CO2, helium, and argon among others. The monitor is well suited for use in confined spaces, cryogenic facilities, and freezers. The monitor will remain accurate at temperatures as low as -40C. PureAire’s durable, non-depleting, long-life zirconium oxide sensor will last for 10+ years in a normal environment without needing to be replaced.
