How to proceed if the gas detector is unreliable
A gas detector is an instrument used to detect gas concentrations. Although it has high detection accuracy, there is a premise that it needs to be calibrated regularly, because if the gas detector is not maintained and calibrated after long-term use It will cause it to measure inaccurately.
The solution to the inaccurate detection of the gas detector
1. When using a gas detector to confirm the accuracy of the gas in the detection environment and the actual concentration, there is a certain difference between the theoretical value and the actual value. It is recommended to calibrate the instrument with a standard gas calibration instrument before use. Ensure the accuracy of instrument testing, or calibrate the instrument through the relevant third-party metrology and verification institutions above the provincial level, because it is difficult for non-professional personnel to deal with the accuracy of such products alone.
2. If the gas detector cannot accurately measure data after calibration, you should communicate with the manufacturer to confirm whether the gas sensor in the instrument can still be used. It can be used normally, but after a period of time, there will still be problems with inaccurate measurement values or excessive drift values, so you can contact the manufacturer to replace the gas sensor in time.
3. If the gas sensor has been used for a period of time, it may cause errors in the measured value, and the detector needs to be recalibrated at this time.
