Description
technical field [0001] The invention relates to the field of gas detection, in particular to a combustible gas detector. Background technique [0002] Combustible gases such as natural gas, liquefied petroleum gas, coal gas, hydrogen, etc. are prone to fire and explosion when exposed to fire or sparks in the air, posing a great threat to life and property. In order to prevent the explosion of combustible gas after reaching a certain concentration and ensure production safety, it is often necessary to install combustible gas detection and alarm devices in factories or places that produce and use combustible gas. The main component of this combustible gas detection and alarm device is a combustible gas sensor, which is usually fixed and can only detect combustible gas at a fixed location. It is very inconvenient when other locations or different locations need to be detected. The portability and ease of use of testing instruments play an important role in the effectiveness of...
