Description
technical field [0001] The invention relates to a gas detector, in particular to a portable gas detector. Background technique [0002] A gas detector is a tool for gas leakage concentration detection, mainly referring to portable / handheld gas detectors. It uses gas sensors to detect the types of gases that exist in the environment. Gas sensors are sensors used to detect the composition and content of gases. It is generally believed that the definition of gas sensors is based on the classification of detection targets, that is to say, any sensor used to detect gas composition and concentration is called a gas sensor, regardless of whether it uses physical methods or chemical methods. The current gas detector has the problems of inaccurate measurement, low measurement accuracy, complex structure, large volume, inconvenient operation and inconvenient to carry. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the abov...
