Introduction to the Classifications of Gas Detectors
A gas detector is an instrument tool for detecting gas leakage concentration. The gas detector can detect various gases such as hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine gas, chlorine dioxide, ozone, and combustible gases. It is widely used for on-site detection in various places such as petrochemicals, coal, metallurgy, chemical industry, municipal gas, environmental monitoring, etc.
Gas detectors can be classified into the following types:
1. Classification by gas type detected
Combustible gas detector, toxic and harmful gas detector, common gas detector;
Advantages of common combustible and toxic gas detection instruments: high cost-effectiveness and good performance.
2. Classified by Function
Single gas detector and multifunctional detector: The single gas detector is mainly used to detect a certain gas in the detection site, and the usage is very large.
Multi functional gas detectors include six in one gas detector, five in one gas detector, four in one gas detector, etc., to meet the needs of different gas detection quantities.
3. Classified by usage method
Portable and fixed: Portable is an instrument that meets the safety requirements of on-site operators for detecting gases before operation, usually depending on the usage scenario.
Fixed type mainly achieves long-term uninterrupted detection to ensure the safety of the usage site, without the need for on-site personnel control, and can be intelligently linked.
4. Classify by sampling method
Diffuse and pump suction: Diffuse gas detectors are widely used and are characterized by their good cost-effectiveness.
Pump suction gas detectors are relatively expensive and mainly meet the special usage needs of special places.
