[0002] As a device for detecting combustible gas in industrial and daily life environments, there are two main types of combustible gas detectors at present. One is fixed, which is generally larger in size and is mostly installed in places where combustible gas is used. The other is handheld. This type of combustible gas detector is usually not used under normal circumstances. It is only used when it is necessary to detect certain specific areas, such as: gas detection in the wild environment or other places where combustible gas exists but it is not convenient to install a fixed combustible gas detector. When using this handheld combustible gas detector, it is generally necessary to place it in a specific area, and it takes a certain amount of time to detect more accurate data.
