1. The accuracy of combustible gas detectors is an important prerequisite for issuing warnings when the concentration of toxic and harmful gases or combustible gases in the detection environment reaches the preset alarm limit. Accurate and timely alarms are guarantees for personnel safety and production safety.

2. The accuracy of the detector mainly depends on the sensor. Electrochemical sensors and catalytic combustion sensors may be gradually altered or poisoned by specific substances in the environment during use. Therefore, regular calibration of gas detectors is completely necessary.

3. At present, all gas detectors have not deviated from relative measurement methods. Therefore, combustible gas detectors must be maintained and calibrated in a timely manner, accurately correcting the manufacturer's requirements to ensure the accuracy of instrument test results.

4. It is also necessary to regularly calibrate the test results of combustible gas detectors to ensure that the error does not exceed the normal range. Like our watches, we must regularly calibrate them together with the standard time to ensure the accuracy of the displayed time.
