Four gas ranges detected by a four in one detector
Among the numerous categories of gas detectors, the four in one detector is currently a very popular product type because it is a composite detector that can detect multiple gases and display the numerical index of four gases or one gas at the same time. Although the four in one detector can detect combustible gases (LEL), oxygen (O2), carbon monoxide (CO), and hydrogen sulfide (H2S), many friends are still not very familiar with the detection range of these four gases. Do you know what are the four gas ranges detected by the four in one detector?
Four gas ranges 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;
The four in one gas detector can simultaneously detect oxygen, hydrogen sulfide, carbon monoxide, and combustible gases. Hydrogen sulfide and carbon monoxide gases can be matched with other gases according to the detection needs of the site. Its unique chip technology greatly improves the response time and stability of gas detection, and greatly improves the battery service life.
Because these four gases are commonly produced during our production or operation processes, they have a significant impact on our life safety. The four core one gas detector is equipped with different gas sensors according to different gases, which is easy to maintain and suitable for combustible gas leakage situations. When a certain gas indicator to be detected is within the alarm range, the instrument will automatically perform a series of alarm actions, flashing lights, vibration, and sound.
In summary, it is the four gas ranges detected by the four in one detector. It is worth noting that during the process of using the four in one detector, in addition to estimating the types of toxic and harmful gases based on experience, we also need to roughly estimate the gas concentration. The alarm value is set by 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 can cause serious damage to the instrument if it is in an over range detection state for a long time.
