Under normal circumstances, the manufacturers of the ammonia gas detector we purchased have already debugged the verification, calibration and calibration work. We only need to connect the signal to use it. However, in many special cases, the ammonia detector needs to be recalibrated or calibrated, but many friends do not know the difference between verification, calibration, calibration and verification. So do you know the difference between Ammonia detector calibration, calibration, and verification? The following is a brief introduction by yi yun Tian:

1:

Ammonia detector uses standard measuring instruments to test the accuracy (precision) of the instruments used.

2. Meaning of verification:

When there are no relevant verification procedures or calibration specifications, it is the 1 way to achieve value transmission and traceability according to the method established by the organization. Mainly used for measuring ammonia gas detector or low precision measuring instrument and test hardware or software.

3. Meaning of calibration:

Under specified conditions, standard equipment and high-precision measuring equipment should be used to test the same Measurement object, and calculate the relative error of the measurement ammonia detector and the standard equipment by group to obtain the correction value of the measurement data of the measurement equipment.

4. Meaning of the verification:

The activity authorization agency that meets the requirements of the legal measurement department or legal measurement agency determines the indication error of the ammonia gas detector, and shall conduct experiments and issue certificates in accordance with the verification procedures.

To sum up, it is the meaning of ammonia gas detector verification, calibration, calibration and verification. By understanding the different meanings and differences between the 4 of verification, calibration, calibration and verification, we can help us to better apply the ammonia detector.
