Among the many categories of gas detectors, the four-in-one detector is currently the 1 product type that is very popular, because it is the 1 composite detector that can detect multiple gases and can simultaneously Display the numerical index of four gases or 1 gases. Although the four-in-one detector can detect the 4 gases of combustible gas (LEL), oxygen (O2), carbon monoxide (CO) and hydrogen sulfide (H2S), many friends still don't know much about the detection range of these 4 gases. Do you know the 4 range of gases detected by the 4-in -1 detector ? The following is a brief introduction by yi yun Tian:

the 4 gas range detected by the four-in-one detector:

1, LEL (combustible gas) range 0-100% LEL or 0-5% CH4;

2, O2 (oxygen) range 0 ~ 30% Vol;

3, CO (carbon monoxide) range 0~500/2000ppm;

4, H2S (hydrogen sulfide) range 0~100/500ppm ;

four-in-one gas detector can simultaneously detect oxygen, hydrogen sulfide, carbon monoxide and combustible gas, among them, hydrogen sulfide and carbon monoxide gas can be selected according to the requirements of the site detection. Its special chip technology greatly improves the response time and stability of gas detection, and at the same time greatly improves the service life of the battery.

Because these 4 gases are common gases produced during our production or operation, and have an impact on our life safety. The quad-core 1 gas detector is equipped with different gas sensors according to different gases, which is easy to maintain and suitable for combustible gas leakage. When a 1 gas indicator to be detected is within the alarm range, the instrument will automatically perform a series of alarm actions, flashing lights, vibrations and sounds.

In summary, it is the 4 gas range detected by the four-in-one detector. It is worth noting that in the process of using the four-in-one detector, in addition to estimating the types of toxic and harmful gases according to experience in advance, we should also roughly estimate the gas concentration and set the alarm value through the gas detector for detection. When the gas concentration exceeds the detection range of the instrument, the detector should be turned off, otherwise, the four-in-one detector will cause serious damage to the instrument when it is in an over-range detection state for a long time.
