gas detector as a key tool for industrial safety, once the problem of improper calibration occurs, it is likely to lead to inaccurate measurement results, affect production safety, increase maintenance costs, etc., resulting in its measurement results deviating from the actual value, unable to accurately reflect the concentration of the measured gas, thus reducing the use efficiency of the gas detector and threatening production safety. So do you know that the gas detector is not calibrated properly, what should you do? The following is a brief introduction by yiyuntian electronics:

1. improper calibration

(1) The calibration cycle is not reasonable:

If the calibration cycle is too long, it may cause the sensor performance to decrease, which may affect the accuracy of the gas detector measurement results.Conversely, if the calibration period is too short, unnecessary calibration cost and effort may be added.

(2) Incorrect calibration method:

Failure to follow the calibration guidelines or relevant standards provided by the gas detector manufacturer, such as using the wrong calibration gas, incorrect calibration procedures, etc, or ignore the inspection and calibration of key components such as internal circuits and sensors of the gas detector.

(3) The calibration environment does not meet the requirements:

There are interference factors in the calibration environment, such as temperature, humidity, electromagnetic interference, etc., which may affect the accuracy of the calibration results of the gas detector. At the same time, if the calibration environment fails to maintain a clean, no target gas state, it is also easy to cause errors in the calibration process.

(4) Not validated after calibration:

After the calibration is completed, the gas detector is not verified with standard gas or other verification methods to confirm the validity of the calibration results.
