Gas detectors can be classified according to the following types:
1. Classification according to the type of detected gas
Flammable gas detector, toxic and harmful gas detector, common gas detector;
Advantages of common flammable and toxic gas detection instruments: high cost performance and good performance.
2. Classification by function
Single detector and multi-function detector: The single gas detector is mainly used to detect a certain gas in the detection site, and the usage is very large.
Multi-function gas detectors include six-in-one gas detectors, five-in-one gas detectors, and four-in-one gas detectors, etc., to meet the needs of different quantities of detected gases.
3. Classification by usage
Portable and fixed: Portable is an instrument that satisfies the on-site operator's safety detection of gas before operation, which is usually related to the usage scenario.
The fixed type mainly realizes long-term uninterrupted detection, so as to ensure the safety of the place of use, does not require on-site personnel control, and can be intelligently linked.
4. Classification by sampling method
Diffusion type and pump suction type: The usage rate of diffusion type gas detectors is very common, and it is characterized by better cost performance.
Pump suction gas detectors are relatively expensive and mainly meet the special needs of special places.
