Gas refers to combustible gases, common types including artificial gas. A gas leak detector is a device that detects gas concentrations, with its core component being a gas-sensitive sensor. Installed in places where gas leaks may occur, it triggers an alarm and emits sound and light signals when the gas concentration in the air exceeds a set value. If connected to an alarm host and emergency response center, it can initiate networked alarms. It can also automatically activate exhaust fans and close gas pipeline valves, ensuring safety of life and property. In civil safety and prevention projects, it is commonly used for household gas leak alarms and is also widely applied in various oil refineries, oil depots, chemical factories, liquefied gas stations, and other places where combustible gas leaks may occur. Faced with the various accident threats caused by gas leaks, is there really no comprehensive solution? According to experts, using 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 gas emissions are the root cause of gas leak emergencies. If gas leaks are detected, timely warnings can be issued. Relevant departments have also concluded, after long-term testing, that the effectiveness of preventing gas poisoning and gas explosion accidents is over 95%.
