How to solve the inaccurate detection of gas detector
1. The gas detector confirms whether the actual concentration of the gas in the detection environment is accurate. The difference between the theoretical value and the actual value is very large. It is recommended to calibrate the instrument with standard gas to ensure the detection accuracy, or send it to the relevant third party above the provincial level. Calibration of metrological verification institutions; it is difficult for non-professional institutions to deal with the accuracy of such products.
2. If the detection 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 for a short time after re-calibration, measurement will still occur after a period of time. If the value is inaccurate and the drift value is too large, it is recommended to contact the manufacturer to replace the gas sensor.
3. If the gas sensor is used for a long time, the measurement value may have errors, and the detector needs to be re-calibrated.
