Det-Tronics PIR9400A3A1AB IR Combustible Gas Detector

Feature & Principle

It adopts NDIR non-dispersive infrared detection principle. Different hydrocarbon gas absorbs specific infrared wavelength. The detector calculates gas concentration by detecting light attenuation. No poisoning risk compared with catalytic bead sensors. It has built-in fault self-check function, can output analog signal to gas alarm controller, suitable for Class I Div 1 explosive hazardous environment.
