【Visual and Audible Alarm】This gas detector emits an alarm when it detects combustible gases in the air. It can react to gas leaks within 2 seconds. Nine colored analog bars and a buzzer help you locate the gas leak. (*Detection time: 50-10000ppm.) High-precision temperature and humidity sensors are added to further measure gas leakage under different conditions.
