No matter what principle is used to detect the four-in-one gas detector, it requires regular calibration and testing. When the four-in-one gas detector is used for a long time, its accuracy is bound to decline due to the influence of sensor loss, use environment or interference gas of the instrument itself. At this time, in order to ensure the accuracy of the four-in-one gas detector, it is very necessary to test and calibrate the four-in-one gas detector. So how often does the four-in-one gas detector need to be tested? Let the staff of Yi Yun Tian explain it to everyone.

detection time of the four-in-one gas detector :

1. the recommended calibration period of the four-in-one gas detector is once in January. if the four-in-one gas detector is not used frequently, such maintenance is not required. In this case, calibration can be performed before each use, and it is recommended that the interval between the calibration date and the use date should not exceed 1 month. In addition to calibration, a functional test is recommended before each use to ensure proper instrument response to gases.

2. The accuracy of the four-in-one gas detector mainly depends on the sensor. Electrochemical sensors and catalytic combustion sensors will be affected by certain substances in the environment during use. The influence of the gas detector changes and even the sensitivity is reduced, so regular calibration of the gas detector is completely necessary.

3. the four-in-one gas detector has not got rid of the relative measurement method, so it needs timely maintenance and correction, and the accuracy of the test results of the four-in-one gas detector calibrated and inspected by the manufacturer can be guaranteed.

4. In order to keep the error of the instrument detection data within the normal range, regular correction is also necessary.

the above 4 points illustrate the detection time of the four-in-one gas detector, hoping to help everyone. in fact, the detection time of the four-in-one gas detector should be determined according to the usage of the gas detector. of course, it is also good if it can be detected regularly.
