Explosion-proof hypoxia monitors are ideal for facilities that use inert gases, including but not limited to nitrogen, helium, and argon. The casing is designed specifically to prevent an ignition explosion. The monitor is ideal for environments where combustible dust and fibers are present, such as corn and grain processing facilities, powder coating plants, and the oil and gas industry. The monitor will remain accurate at -40C. PureAire's durable, lossless zirconia sensors last for more than 10 years in normal environments where they need to be replaced.
