PureAire 99033 Oxygen Deficiency Monitor, 0-95%

The PureAire Oxygen 0-95% Monitor is perfect for facilities that use inert gases including, but not limited to, nitrogen, CO2, helium, and argon. The monitor is well suited for use in confined spaces, cryogenic facilities, freezers, and in locations where an oxygen-enriched environment is necessary. 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.

Features:

• Long Life 10 + Year Sensor

Long-Lasting O2 Zirconium Sensor

The PureAire 0-95% Oxygen Monitor features a long-lasting zirconium oxide sensor that provides accurate readings for 10+ years with no scheduled maintenance.

PureAire's 0-95% O2 Monitor is suitable for a wide range of uses. From bar and restaurant beverage stations to tire repair centers, food processing plants, agricultural grow facilities, and hospitals, 0-95% Oxygen Monitors safely track nitrogen, argon, helium, and CO2 gas levels. The Monitor will alert users when oxygen levels reach an unsafe level, either too low or too high. Our zirconium O2 sensor performs reliably in temperatures ranging from 55 Celsius to -40 Celsius, so it's ideal for environments including freezers, cryogenic facilities, and frozen food manufacturing plants. The low-maintenance and long-lasting sensor provides continuous monitoring in applications where inert gases such as nitrogen, helium, argon, and carbon dioxide are used or stored. Once set up, the O2 zirconium sensor will operate continuously.
