Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a combustible gas detection alarm. Background Art

[0002] The combustible gas detection alarm is a gas leak detection alarm instrument. When combustible or toxic gas leaks in an industrial environment, when the gas alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the combustible gas alarm will send out an alarm signal to remind workers to take safety measures and drive the exhaust, cut-off, and spray systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production. The combustible gas detection alarm can measure various gas concentrations;
