1. The combustible gas detector is a detector installed in industrial and civil buildings that responds to the concentration of single or multiple combustible gases. The most commonly used flammable gas detectors are catalytic type flammable gas detectors and semiconductor type flammable gas detectors. In restaurants, hotels, and family production rooms, where gas, natural gas, and liquefied gas are used, semiconductor-type flammable gas detectors are mainly used, and industrial places emitting combustible gas and flammable steam mainly use catalytic flammable gas detectors.
