- [Explosion Proof Oxygen Monitor, 0\-25%, Incl 10\+ Year Sensor](https://www.pureairemonitoring.com/air-check-o2-ex-oxygen-deficiency-monitor/99132-99133-99134-99136/): \PureAire's Explosion Proof Oxygen Deficiency Monitor is engineered for high\-risk environments where inert gases such as nitrogen, helium, or argon are used\. Designed with a rugged, explosion\-proof enclosure, this monitor prevents ignition in areas with flammable dust, gases, or fibers—making it ideal for grain processing facilities, powder coating plants, oil and gas refineries, and similar hazardous locations\.\
\Built to perform in extreme conditions, the monitor remains accurate in temperatures as low as \-40°C\. At its core is PureAire’s long\-life zirconium oxide sensor, which delivers reliable, non\-depleting performance for over 10 years in typical use—eliminating the need for frequent sensor replacement and reducing long\-term maintenance costs\.\
- [Replacement Filter](https://www.pureairemonitoring.com/product/replacement-filter/): PureAire's disposable high\-efficiency filters help protect sensitive flow controllers and the internal vacuum pump in our gas monitoring equipment from ambient contamination\.
