What gases does a 4 gas monitor detect

Among the many classifications of gas detectors, the 4 gas monitor is currently a very popular product category because it is a combination detector that can detect multiple gases and can display a numerical index for four gases or one gas at a time. Commonly used 4 gas monitor can detect combustible gases (LEL), oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S) of the four gases, but also according to the needs of the different sensor probe can be customized to monitor the other gases, this article introduces What gases does a 4 gas monitor detect and detection range.
4 gas monitor detects four gas ranges:
1, LEL (combustible gases) range 0-100% LEL.
2、O2 (Oxygen) range 0 ~ 30%Vol.
3, CO (carbon monoxide) range of 0 ~ 1000ppm.
4、H2S(Hydrogen Sulfide) Range 0~100/500ppm ;)
What gases does a 4 gas monitor detect
4 gas monitor can simultaneously detect oxygen, hydrogen sulfide, carbon monoxide and combustible gases, of which hydrogen sulfide and carbon monoxide gases can be selected according to the needs of the place of detection of other gases, its sensor probe technology greatly improves the response time and stability of the gas detection and other performance, and at the same time significantly improve the battery life.
Because these four gases are common in our production or operation process of the gas generated, the safety of our lives have an impact. 4 gas monitor according to different gases equipped with different gas sensors, easy to maintain, applicable to the leakage of combustible gases. When a 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.
4 gas monitor application
4 gas monitor has a wide range of applications, can be used for fire scene safety inspection, petroleum, chemical, metallurgy, mining, fire, gas, environmental protection, electric power, communications, paper, printing and dyeing, food reserves, urban water supply, sewage treatment, food, scientific research, education, national defense and other fields.
To summarize, it is What gases does a 4 gas monitor detect and the detection range. It is worth noting that we use the 4 in 1 detector in the process of detection, before the detection, in addition to prior to estimate the type of toxic and hazardous gases based on experience, but also roughly estimate the gas concentration, through the gas detector to set the alarm value for the detection of the gas detector, when the gas concentration exceeds the detection range of the instrument, to turn off the detector, or else the 4 in 1 detector for a long time in the detection of the over-range state will make the instrument cause serious damage.
