when we are in the process of using the gas detector, many friends have said that they have encountered inaccurate detection of the gas detector, so that the detection of the gas detector cannot be carried out smoothly, which not only has a serious impact on our work, but also poses a serious threat to our health. However, for the sake of safety, when we encounter a failure problem during the use of the gas detector, do not blindly panic to deal with it, so as to avoid some unprofessional operations that cause damage to the parts of the testing instrument. So how do we solve the gas detector detection inaccuracy? The following is a brief introduction by yi yun Tian:

How to solve the inaccurate detection of gas detector:

1. confirm whether the actual concentration of gas in the environment detected by the gas detector is accurate. if there is a large difference between the theoretical value and the actual value, it is recommended to use standard gas calibration instruments to ensure the detection accuracy, or send it to relevant third-party metrological verification institutions above the provincial level for verification and calibration; it is difficult for non-professional people to deal with the accuracy of such products.

2. if the detection is not accurate after calibration, it is necessary to confirm with the manufacturer whether the gas sensor can continue to be used. if the sensor itself is approaching its service life, even if it can be used normally within a short period of time after recalibration, the measurement value will still be inaccurate after a period of time, as well as the drift value is too large, it is recommended to contact the manufacturer to replace the gas sensor.

3. If the gas sensor of the gas detector is used for a long time, the measured value may have certain errors. At this time, we need to recalibrate the gas detector.

In summary, it is the way to solve the inaccurate detection of gas detectors.The installation of the gas detector can effectively detect hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone and combustible gases and other gases. It can be widely used in petrochemical, coal, metallurgy, chemical, municipal gas, environmental monitoring and other places on-site detection. At the same time, it can also realize the measurement needs of special occasions, especially for gas concentration detection or leak detection in tunnels, pipelines, tanks, confined spaces, etc.
