• An O₂ explosion proof monitor is for use in environments that require Class I, div I, Group B,C,D, and div 2 Group E,F, G Enclosures. This monitor is specifically designed to not be a source of ignition. It is ideal for use in spaces with highly combustible gases. This includes facilities that use blanketing with cryogenic gases, including nitrogen, or facilities using high concentrations of oxygen. We can also adapt this monitor to be safe for use in class II environments upon request. This will be well suited for spaces with highly combustible dust or particles. This uses a 10+ year zirconium oxide sensor.
• Also available in Class II dust configurations. Contact PureAire for details.

Why choose PureAire?

• As an industry leader in oxygen monitoring and gas detection, PureAire is dedicated to the safety of our clients, and the customers they serve, by manufacturing monitors that are long-lasting, innovative, and reliable.

What gases can an Explosion Proof O2 Monitor be used for?

• PureAire’s oxygen monitors can be used for nitrogen, argon, CO₂, and helium gases.
• The Explosion Proof Oxygen Monitor offers long-lasting O₂ deficiency detection. PureAire's oxygen monitors are designed to be reliable, affordable, low maintenance, and provides continuous monitoring for an average of 10 years and more.
• Ideal for use in electrically classified locations, confined spaces, analyzer shelters, petrochemical plants, cryogenic gas storage, and locations requiring remote sampling. The EX 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 -40°C.
• The monitor features an easy-to-read local display, visual LED’s, and audible alarm. The oxygen monitor can be linked to fire alarm systems for notification of all employees.
• The zirconia sensor is not sensitive to temperature, humidity, or barometric pressure changes (including thunderstorms). Unlike other oxygen monitors, replacement sensors are not required, since we use a zirconium sensor, rather than a disposable electrochemical sensor lasting 1-2 years on average. Supervised watchdog software runs 24/7 checking electronics and components. Any errors or inconsistencies are reported on the display.
