Gas is any combustible gas, common types include: coal gas, natural gas. A gas leak detector is a device that detects gas concentrations, with its core component being a gas-sensitive sensor, installed in locations prone to gas leaks. When the gas concentration in the air exceeds the set threshold, the detector triggers an alarm and emits an audible and visual alarm signal. If connected to an alarm host and a receiving center, it can enable networked alarms. It can also automatically activate exhaust equipment and close gas pipeline valves, ensuring the safety of life and property. In civil safety protection projects, it is commonly used for residential gas leak alarms and is also widely applied in various oil refineries, oil depots, chemical plants, liquefied gas stations, and other places where combustible gas leaks can occur. In the face of the various accident threats caused by gas leaks, does there really not exist a comprehensive solution? According to some experts, the use of gas leak detection is one of the important means to combat the invisible killer of gas. Gas experts point out that gas poisoning incidents resulting from gas leaks or waste emissions are the root cause, and timely warnings can be obtained by detecting gas leaks. Relevant departments have also concluded through long-term testing that the effectiveness of preventing gas poisoning and gas explosion accidents exceeds 95%.
