Description

Technical Field

[0001] The utility model relates to the technical field of gas detection, in particular to a gas detector. Background Art

[0002] Gas detectors usually use gas sensors to detect gases, and different gases use different sensors. Semiconductor gas sensors can be effectively used to detect many gases such as methane, ethane, formaldehyde, carbon monoxide, acetylene, vinyl chloride, etc., and they are low-cost. They are made of some metal oxide semiconductor materials and are manufactured on the principle that the conductivity changes with the change of ambient gas composition at a certain temperature. In order to cope with the range of gases detected, the sensor components of the gas detector are usually designed to be detachable.

[0003] Although the sensors of some current gas detectors can be replaced, they are still relatively fixedly installed on the detector body. During actual detection, the sensor and the instrument body need to be in the same position. However, for some relatively narrow detection locations such as the inside of some pipes and deep in gaps, the instrument body cannot enter and thus cannot perform detection work. There are certain limitations in the application scenarios. Utility Model Content
