In many fields, basically all occasions that need to detect gas concentration need to use a four-in-one gas detector. This instrument has high detection accuracy, rapid response, and sensitive response, which is not only applicable Stronger, and the reliability and service life are also very long, such as oil, natural gas, paint, painting plants, mining, metallurgy, communications, fire protection, catering, gas stations, gas stations, power plants, municipal engineering and other places need to be applied. Do you know the range of gases that can be detected by 4-in -1 gas detector ? The following is a brief introduction by yi yun Tian:

four-in-one gas detector can detect the type and scope:

1. LEL of combustible gas-detection range: 0-100% LEL or 0-5% CH4

2. Oxygen O2-detection range: 0 ~ 30% Vol

3. CO CO-detection range: 0~500/2000 ppm

4. Hydrogen sulfide H2S-detection range: 0~100/500 ppm

the four-in-one gas detector can simultaneously detect oxygen, hydrogen sulfide, carbon monoxide and combustible gas, of which hydrogen sulfide and carbon monoxide gas can be selected according to the needs of on-site detection, the four-in-one gas detector chip technology greatly improves the response time and stability of gas detection, and greatly improves the service life of the battery.

In summary, the four-in-one gas detector can detect the type and scope of gas. Generally speaking, the four-in-one gas detector detects oxygen, hydrogen sulfide, carbon monoxide and combustible gas. It is the 1 gas detection and alarm instrument that can detect and display the concentration value of 4 kinds of gas at the same time and give sound, light and vibration alarm when it exceeds the limit.
