7 Common Classifications of Gas Detectors
1. Classification by function:
There are single detectors and multi-functional detectors: single gas detectors are mainly used to detect a certain gas in the detection place, and the usage is very large. The multi-function gas detectors include six-in-one gas detectors, five-in-one gas detectors, four-in-one gas detectors, etc., to meet the needs of different gas detection quantities.
2. According to the detection gas classification:
There are flammable gas detectors, toxic gas detectors, common gas detectors, and special gas detectors; the price of common flammable and toxic gas detectors usually ranges from several hundred to several thousand, while the price of special gas detectors is in the It can range from thousands to tens of thousands. Common flammable and toxic gas detection instruments have the advantages of high cost performance and good performance, while special gases can meet special inspection needs and have high accuracy, but they are expensive.
3. Classification by place of use:
There are conventional type and explosion-proof type: the conventional type is produced according to the national standard and can meet the needs of all environments. The price ranges from several hundred to several thousand. The explosion-proof type meets all detection needs in special places, and the price is slightly more expensive.
4. Classification by users:
Household and industrial use: The price of household gas detectors ranges from tens to hundreds of yuan. Cut off at the source. The indicators of industrial gas detectors are very high. They must meet the safety standards used in various places such as national standards and industry standards. The price ranges from several hundred to several thousand.
5. Classified by usage:
There are portable (hand-held) and fixed (mounted, wall-mounted): portable instruments that meet the needs of on-site operators to detect gas safely before work, usually related to the usage scenario. The fixed type mainly realizes long-term uninterrupted detection, so as to ensure the safety of the site, does not require on-site personnel to control, and can be intelligently linked.
6. Classified by sampling method:
There are diffusion type and pump suction type: the usage rate of diffusion gas detectors is very common, and the price is relatively low, ranging from several hundred yuan to several thousand yuan. The price of the pump-suction gas detector is relatively high, usually ranging from several thousand yuan or more, mainly to meet the special needs of special places.
7. Classification according to the detection principle:
Combustible gas detection includes catalytic combustion type, semiconductor type, thermal conductivity type and infrared absorption type, etc.; toxic gas detection includes electrochemical type, semiconductor type, etc.
