The Combustible/Toxic Gas Detector’s instrument fault supervision circuitry continuously monitors for failed sensor cells and communication line breaks. Plus, sensor cell operation is continuously supervised 24/7, and when used in conjunction with distributive control systems or PLCs, it provides immediate fault identification for a disconnected sensor cell.

PureAire’s Combustible/Toxic Gas Detector is housed in a NEMA 7 explosion-proof enclosure suitable for Class 1, Division 1 and 2, Groups A, B, C, and D. The gas detector can be used to detect Carbon Monoxide, IPA, Hydrogen, Hydrogen Sulfide, Ethanol, Propane, and other toxic gases. Capable of monitoring ppm levels of toxic gas or % LEL levels of combustible gases, it is a perfect monitoring solution for providing worker protection in chemical plants, refineries, and other areas requiring hazardous classifications.
