What to do if the gas detector measures inaccurately
A gas detector is an instrument used to detect gas concentration. Although it has high detection accuracy, a prerequisite is that it needs to be calibrated regularly, because if the gas detector is not maintained and calibrated after long-term use, it will result in inaccurate measurements.
Solution to inaccurate detection of gas detector
When using a gas detector to confirm whether the gas in the detection environment is accurate compared to 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 to ensure the accuracy of the instrument detection. Alternatively, the instrument can be calibrated by a third-party metrological verification institution at or above the provincial level, as it is difficult for non professional personnel to handle the accuracy issues of such products alone.
If the gas detector cannot accurately measure data after calibration, it should be communicated with the manufacturer to confirm whether the gas sensor in the instrument can continue to be used. If the sensor itself has exceeded its service life, although it can still be used normally after recalibration for a short period of time, problems such as inaccurate measurement values or excessive drift values may still occur after a period of time. Therefore, the manufacturer can be contacted to replace the gas sensor in a timely manner.
If the gas sensor has been in use for a period of time, it may cause measurement errors and require recalibration of the detector.
