I believe everyone knows that the emergence of the four-in-one gas detector effectively solves the perception of colorless and odorless dangerous gases, and better protects the lives of relevant operators. In order to better ensure safety, before using the four-in-one gas detector, we need to understand its range first, and then set the appropriate range value according to our actual situation. So do you know 4-in -1 gas detector what is the normal range? The following is a brief introduction by yi yun Tian:

4-in -1 gas detector general range, as follows:

in general, the conventional range of the four-in-one gas detector is: 0-1ppm, 5ppm, 10ppm, 20ppm, 50ppm, 100ppm, 200ppm, 500ppm, 1000ppm, 2000ppm, 5000ppm, 10000ppm, 50000ppm, 100%Lel 0-2% Vol, 5% Vol, 10% Vol, 30% Vol optional. Conventional oxygen selection 0-30% VOL, hydrogen sulfide selection 0-100PPM, carbon monoxide selection 0-1000PPM , combustible choice 0-100% LEL.

the resolutions corresponding to different measuring ranges are also different. the resolutions we often encounter are generally,. 01 ppm or 0.001ppm(0 ~ 1ppm);0.01ppm(0 ~ 100ppm);0.1ppm(0 ~ 999ppm);1ppm(1000ppm and above); 0.1%Vol(0 to 100%Vol) or 0.01%Vol(0 to 100%Vol);0.1% Lel(0 to 100% Lel). At present, the detection range of Yiyuntian's MS600 portable four-in-one gas detector is CO(0 ~ 1000ppm), H2S(0 ~ 100ppm), O2(0 ~ 30% Vol), Ex(0~100 LEL). Other ranges can be customized and you can choose according to your own needs.

To sum up, it is the conventional range of the four-in-one gas detector. By using four-in-one gas detectors in agriculture, chemical industry, construction, electric power, fire protection, natural gas, steel industry, petroleum and petrochemical, sewage treatment and other fields, we can well detect the concentration of 4 kinds of gases such as oxygen sulfide, carbon monoxide, oxygen, combustible gas, etc. When the concentration exceeds the alarm value, vibration and sound alarms can be provided to prompt the staff to take relevant safety measures and stay away from danger immediately.
