How to calibrate the nitrogen oxide analyzer
1. We need to prepare the corresponding standard gas, and at the same time, align the calibration cover with the probe to be detected by the nitrogen oxide analyzer, and turn on the standard gas.
2. The calibration starts, and waits for the calibration gas to enter the nitrogen oxide analyzer. When a certain value is reached, the controller of the nitrogen oxide analyzer in the central control will sound an alarm. At this time, we press the reset button to cancel the alarm. After the alarm is cancelled, take off the calibrated calibration gas cover, and then close the on-off valve of the container containing the standard gas.
3. We record the gas concentration displayed on the central control. We must pay attention during the calibration process. When using standard gas for calibration, the nitrogen oxide analyzer probe must be cleaned, and the standard sample gas must be turned on for more than ten seconds.
To sum up, it is the calibration procedure of the nitrogen oxide analyzer. In actual use, many factors will affect the accuracy of the detection data of the nitrogen oxide analyzer. Therefore, in order to ensure the accuracy of the detection data, we need to calibrate the nitrogen oxide analyzer regularly, so that the effective The error of the detection result can be greatly reduced, so as to improve the accuracy.
