I believe everyone knows that it is very necessary to calibrate the four-in-one gas detector during use, because we mainly judge the gas concentration in the current environment according to the value detected by the instrument. If the value displayed on the four-in-one gas detector is wrong, it will lead to our judgment error. Therefore, when the four-in-one gas detector is not accurate, it will undoubtedly bring great inconvenience to our detection work. So do you know that four-in-one gas detector has inaccurate detection, what should you do? The following is a brief introduction by yi yun Tian:

4-in -1 gas detector:

1. confirm whether the gas concentration on site is accurate and the difference between the theoretical value and the practical value is very large. it is recommended to calibrate the gas detector through standard gas to ensure the detection accuracy or send it to a third-party metering institution for verification and calibration.

2. if the gas sensor is used for a long time and the four-in-one gas detector is still inaccurate 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 measured value will still be inaccurate and the drift value will be too large after a period of time. It is recommended to contact the manufacturer to replace the gas sensor.

To sum up, it is the treatment countermeasure for the inaccurate detection of the four-in-one gas detector. Through the above methods, we can effectively solve the inaccuracy of the four-in-one gas detector, ensure the accuracy of the detection data, and thus ensure the smooth progress of the gas detection work more effectively.
