industrial gas alarm

Portable combustible gas detectors (hereinafter referred to as detectors), is a continuous detection of combustible gas concentration for explosion-proof requirements of intrinsically safe place equipment. Detector using diffusion sampler, the measured gas concentrations in the scene into electrical signals, processed by the internal circuitry in the LCD display directly detect gas concentrations; When measured gas concentrations in high and low limit alarm value, the detector will an alarm sound and flashing red light signal.
