The Air Check Explosion Proof Combustible Gas Monitor is ideal for facilities that require continuous monitoring of toxic and corrosive gases in hazardous areas. The enclosure is specifically designed to prevent an explosion. The monitor is well suited for environments such as power plants, refineries, natural gas locations, and the oil and gas industry, and anywhere combustible, toxic gases are present. 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 4-5 years in a normal environment without needing to be replaced.
The instrument’s fault supervision circuitry continuously monitors for failed sensor cell and communication line breaks. Plus sensor cell operation is continuously supervised 24/7 and when used in conjunction with distributive control systems or PLC’s, provides immediate fault identification for a disconnected sensor cell.
The Air check LEL gas detector is housed in a Nema 4 explosion proof enclosure and is available for Ethanol, hydrogen, natural gas, methane, and more . Capable of monitoring the % LEL combustible gases, the Air check Ex is a perfect monitoring solution for providing worker protection in chemical plants, refineries and other areas requiring hazardous classifications.
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.
