Generally, when we use gas detectors for gas detection in our daily life, we will encounter various fault problems. For example, what if the gas concentration value detected by the gas detector is not accurate? How to deal with it?
First of all, when we encounter fault problems during the use of the gas detector, we should not deal with them blindly in a panic, in order to avoid some unprofessional operations that may damage the parts of the detector.
If it is confirmed that the gas detector is not accurate in detecting the actual concentration of the gas in the environment, and the deviation between the theoretical value and the actual value is large, it is recommended to use the standard gas calibration instrument to ensure the detection accuracy, and send it to the factory for calibration or to the relevant third party metrological verification institution at or above the provincial level for verification and calibration. It is difficult for personnel of non-professional institutions to deal with problems such as product accuracy.
How to solve the inaccurate detection of gas detector:
resolvent:
1. The gas detector shall confirm whether the actual concentration of the gas in the detection environment is accurate, and the deviation between the theoretical value and the actual value is large. It is recommended to use the standard gas calibration instrument to ensure the detection accuracy, or send it to the relevant third-party metrological verification institution at or above the provincial level for verification and calibration; It is difficult for non-professional personnel 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 still be used. If the sensor itself is approaching its service life, it can still be used normally even if it is recalibrated for a short time. After a period of time, the measured value will be 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 measured value may have errors, and the detector needs to be recalibrated.
