The Difference Between Verifying, Calibrating, and Verifying Gas Detectors
Gas detectors help factories solve gas safety problems during industrial production. But it is also a precision instrument that needs to be understood and used correctly to function as it should. But in fact, when we use gas detectors, we will fall into some misunderstandings. For example, we think that calibration, calibration, calibration, and calibration are the same. In fact, this is a wrong understanding. Then the gas detector calibration, calibration, calibration, and verification are specific. What are the differences?
1.Calibration
Operation that improves the accuracy (precision) of an instrument or system by compensating for instrument system errors by measuring deviations from a standard. Calibration is generally used for higher precision instruments.
2. Verification
According to the national metrological verification regulations, it is an activity to determine through experiments whether the indication error of measuring instruments meets the requirements. The scope of calibration is a measuring instrument that is compulsorily calibrated as clearly stipulated in my country's Measurement Law.
3.Calibration
The activity of determining the indication value of measuring instruments through experiments according to relevant calibration specifications. Usually, the error of the instrument being measured relative to the standard instrument is measured by comparing it with a higher-precision standard instrument, thereby obtaining the correction value of the indication value of the instrument being measured. Calibration is mainly used for measuring instruments that are not subject to mandatory verification.
4. Verification
When there are no relevant verification procedures or calibration specifications, it is a way to implement value transfer traceability according to the organization's own method. Mainly used for measuring instruments or measuring instruments with relatively low accuracy.
The main differences between calibration, verification, calibration and verification of gas detectors:
Calibration is a dynamic process that rechecks the accuracy of the test equipment during measurement and eliminates errors in a timely manner.
Secondly, verification, calibration and verification are static measurement processes carried out on a periodic basis.
General selection methods for verification, verification and calibration:
1. Belongs to the national compulsory inspection catalog and is submitted for inspection;
2. If it is not in the national compulsory calibration catalog but has JJG or JJF, it must be submitted for inspection/calibration, or if the company has standard equipment, instruments and calibration methods, it can perform self-calibration;
3. If there is no JJG or JJF, please verify it yourself.
