combustible gas alarm is currently the 1 instrument specially used for detecting combustible gas. when combustible gas exists in the measured place, the detector converts the gas signal into a voltage signal or a current signal and transmits it to the alarm instrument, and the instrument shows the percentage concentration value of the lower explosive limit of combustible gas. When the concentration of combustible gas is higher than the alarm set value, an audible and visual alarm signal will be issued, and the personnel on duty will take timely safety measures to prevent the occurrence of explosion accidents.

Almost all chemical plants, integrated circuit workshops, gas laboratories, oil refineries, power plants, gas company pressure regulating stations, oil production wells, gasoline storage and transportation, gas stations, large canteens, public places to detect air quality, steel plants, coal mine food packaging, pharmaceuticals, oil depots, underground parking lots, family kitchens, biogas stations, etc. In addition, it also includes first-class explosion-proof places, hotel kitchens, restaurants, canteens, boiler rooms, liquefied gas stations, and all units that use, store, manufacture, and contain combustible gas must install combustible gas alarms.
