What Are the Categories of Gas Detection Instruments for Application Scenarios?
As is well known, gas detection is a very necessary task for safety protection. Gas detectors can effectively ensure gas detection in limited spaces and ensure the safety of the space. However, due to different application scenarios, there are currently many types of gas detectors, which can be subdivided into many gas detectors according to different classifications. Do you know the common classifications of gas detectors?
Common classifications of gas detectors:
1. Classified by function:
There are single gas detectors and multifunctional detectors: single gas detectors are mainly used to detect a certain gas in the detection site, and the usage is very large. And multifunctional 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.
2. Classified by detected gas:
There are combustible gas detectors, toxic gas detectors, common gas detectors, and special gas detectors; The prices of common combustible and toxic gas detection instruments usually range from a few hundred to several thousand, while the prices of special gas detection instruments range from several thousand to tens of thousands. The advantages of common combustible and toxic gas detection instruments are high cost-effectiveness and good performance, while special gases meet special inspection needs and have high accuracy, but are expensive.
3. Classified by usage location:
There are conventional and explosion-proof types: Conventional types are produced according to national standards to meet all environmental needs, with prices ranging from a few hundred to several thousand, and the characteristic is excellent cost-effectiveness. Explosion proof type meets the testing needs of special fields and is slightly more expensive.
4. Classified by user group:
For both household and industrial use: The price of household gas detectors ranges from tens to hundreds of yuan, with excellent cost-effectiveness and convenient use. They only need to be placed in a designated location and plugged into a power source to work, and can be linked with a gas cut-off valve to achieve automated processing and cut off hidden dangers from the source. Industrial gas detectors have very high requirements for various indicators and must meet safety standards such as national and industry standards for use in various places. The price ranges from several hundred to several thousand yuan.
5. Classified by usage:
There are portable (handheld) and fixed (installed, wall mounted) instruments: portable instruments that meet the safety requirements of on-site operators for detecting gases before operation, usually depending on the usage scenario. The fixed type mainly achieves long-term uninterrupted detection to ensure the safety of the site, without the need for on-site personnel control, and can be intelligently linked.
6. Classified by sampling method:
There are diffusion type and pump suction type gas detectors: diffusion type gas detectors are widely used and have relatively low prices ranging from a few hundred yuan to several thousand yuan. The price of pump suction gas detectors is relatively high, usually ranging from a few thousand yuan or more, mainly to meet the special needs of special places.
7. Classified by detection principle:
Combustible gas detection includes catalytic combustion type, semiconductor type, thermal conductivity type, and infrared absorption type; Toxic gas detection includes electrochemical and semiconductor types.
