In order to ensure the accuracy of the test results, we need to calibrate regularly during the use of combustible gas alarms. Its calibration mainly refers to the use of standard measuring instruments to detect whether the accuracy (precision) of the instruments used meets the standard. Especially when the reading of the host is high or low, and the reading of the host is unstable, it is necessary to re-calibrate the combustible gas alarm. Do you know what to pay attention to when combustible gas alarm is marked? The following is a brief introduction by yi yun Tian:

Combustible gas alarm calibration should pay attention to the following:

1. Calibrate environmental conditions.

The error in the verification of combustible gas alarm mainly comes from the verification environment. Therefore, the detector should be installed as far as possible in a place where there is no wind, no dust, no water, no impact, no vibration, no corrosion, and away from electromagnetic interference.

2. Calibrate flow control.

Since the flow of the combustible gas alarm may directly affect the accuracy of the verification results, it is necessary to control the flow. Flow is too large, or too small, will affect the calibration results.

3. Calibration mask for calibration.

calibration cover will be used when calibrating combustible gas alarm. each manufacturer has its own special calibration cover. when calibrating, it is better to use the original calibration cover, and the calibration result will be more accurate. In addition, in order to ensure the accuracy of detection, the combustible gas alarm shall be calibrated at least once in March and June.

To sum up, there are some things to pay attention to when the combustible gas alarm is marked.Combustible gas alarm as a measuring instrument, do a good job of calibration is to ensure the safety of the key link, therefore, in order to ensure safety, we in the combustible gas alarm calibration, we must pay attention to these matters, so as to better ensure the smooth progress of the detection work.
