The Air Check Explosion Proof Combustible Gas Monitor is ideal for facilities that require continuous monitoring of Ethanol and Alcohol based products. The enclosure is specifically designed to prevent an explosion. The monitor is well suited for environments such as Hand Sanitizer locations, Ethanol plants, combustible gas locations requiring LEL gas analyzers, chemical plants, and where air sampling is required for combustible gases in vessels under a nitrogen blanket. The monitor is housed in a NEMA 4 explosion-proof enclosure suitable for Class 1, Group B, C, and D, Class 2, Group E, F, and G. PureAire’s durable, long-life LEL catalytic sensor will last 5-6 years in a normal environment without needing to be replaced.

The Air check LEL gas detector is housed in a Nema 4 Explosion Proof Enclosure and is available for Ethane, Ethanol, or Alcohol. Capable of monitoring the percentage of LEL combustible gas, the Air check Ex is a perfect monitoring solution for providing worker protection in had sanitizer plants, retrofitted refineries or distilleries, and other areas requiring hazardous classifications for alcohol based products. Commonly paired with oxygen sensors for vessels under Nitrogen, the ethanol sensor can be used for ethanol vessels or for safety nearby for employee protection.
The instrument’s fault supervision circuitry continuously monitors for failed sensor cell and communication. Our sensor cell operation is continuously supervised 24/7, and when used with distributive control systems or PLC’s, the monitor provides immediate fault identification.
The PureAire Air check Ex incorporates sophisticated electronics which, when used in conjunction with distributive control systems or PLC’s enable you to quickly identify and correct major system faults. These enhanced self-diagnostic capabilities include missing cell and broken transmitter wiring. Should a system error occur, the Air check Ex outputs a 0 mA signal to remote alarm/control systems to immediately alert control room personnel.
