The household series flammable, explosive and toxic gas leakage alarms are made of high-quality gas-sensitive components, combined with advanced electronic technology and sophisticated technology; In households, factories, and other places where combustible gases and toxic gases exist, once the leakage concentration of liquefied petroleum gas, natural gas, artificial gas, carbon monoxide, hydrogen and other gases reaches the set warning value, the alarm will send an alarm signal, and can start solenoid valves, exhaust fans and other external equipment to automatically eliminate hidden dangers. The gas alarm will faithfully send out audible and visual alarm signals to remind you to take effective measures immediately; or start the linkage device, ventilate or close the air source to eliminate the danger; Effectively avoid the occurrence of fire, suffocation, death and other vicious accidents.
