Natural gas refers to combustible gases, with common types including coal gas. A gas leak detector is a device that detects the concentration of gas, with its core component being a gas-sensitive sensor. Installed in locations prone to gas leaks, the detector triggers an alarm when the gas concentration in the air exceeds a set value, emitting both audible and visual alarm signals. If connected to an alarm host and an emergency response center, it can initiate networked alarms. Additionally, it can automatically activate exhaust fans, close gas pipeline valves, and ensure safety of life and property. In civil safety protection projects, it is commonly used for home gas leak alarms and widely applied in various refineries, oil depots, chemical plants, liquefied gas stations, and other places where flammable gas leaks may occur. Faced with the threats of accidents 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 crucial methods to combat the invisible killer of gas. Gas experts point out that gas poisoning incidents largely stem from gas leaks or exhaust emissions, and timely warnings can be obtained through gas leak detection. Authorities, after long-term testing, have also concluded that the effective rate of preventing gas poisoning and gas explosion accidents exceeds 95%.
