Description [Applicable to multiple gas leakage detection]: propane gas detector is applicable to detection of liquefied petroleum gas (propane and methane), natural gas, coal gas, natural gas fuel, artificial gas, liquefied petroleum gas, liquefied natural gas, etc. [Suitable for multiple scenarios]: The natural gas detector can be used as an independent home alarm device, or as a front-end sensor of the alarm system. It is widely used in restaurants, hospitals, hotels, oil plants, garages, gas stations, etc. [Strong quality and function]: The natural gas detector adopts high-quality semiconductor heating sensor. Visual and auditory alarm function of gas leakage detector MCU intelligence. When the gas alarm detects a gas leak, the concentration of the LED display will change and an alarm of 85 dB or more will be given. [Easy to install]: The gas leakage sniffer is designed to be easy to install, and can be directly plugged into the power socket to detect leakage gas. [Warm prompt]: The system warm-up time is about 2-3 minutes. During this time, the gas test will not work. You need to wait for the display screen to display 0 (the system enters the working state) before you can test normally.
