PureAire Monitoring Systems’ Explosion Proof Oxygen Monitor offers long-lasting O2 deficiency detection in a robust, explosion-proof format. Like the rest of PureAire’s oxygen monitors, our Explosion Proof Oxygen Monitor is reliable, affordable, maintenance-free, and designed to provide continuous monitoring for 10+ years.
Ideal for use in laboratories and confined spaces, including freezers, cryogenic gas storage areas, and hyperbaric chambers, the oxygen monitor can detect leaks of inert gases such as nitrogen, helium, and argon. The Explosion Proof Oxygen Monitor can detect gas leaks at temperatures as low as -40C. Its long-lasting zirconium oxide sensor reliably monitors oxygen levels with no calibration or maintenance required.
The monitor features a joystick controller, easy-to-read local display, visual alarm, and audible alarm. The oxygen monitor can be linked to fire alarm systems for robust notification of all employees.
PureAire Monitoring Systems’ Explosion Proof Oxygen Monitor is easy to set up and runs automatically once installed. The unit is not sensitive to temperature, humidity, or barometric pressure drops (including thunderstorms). Unlike other oxygen monitors, the unit requires no maintenance and no calibration, since we use the zirconium oxide sensor rather than a fussy electrochemical sensor. “Supervised watchdog” software runs 24/7, checking all components of the unit. Any errors or inconsistencies are reported on the display.
By switching to PureAire’s Explosion Proof Oxygen Monitor, you can save as much as $400 annually and reduce the time-intensive cycle of replacing sensors and calibrating oxygen monitors.
