Metrology calibration

Metrology calibration

Measurement is an activity to achieve unity of units and accurate and reliable measurement values. In other words, it is a measurement aimed at achieving unity and accurate and reliable measurement. It involves the entire measurement field, and in accordance with the law, plays a role in guiding, supervising and guaranteeing measurement

The basic requirements of calibrationThe basic requirements that should be met by calibration are as follows:

1) Environmental conditions: If the calibration is carried out in a laboratory, the environmental conditions should meet the requirements of the laboratory for temperature and humidity. If the calibration is carried out on site, the environmental conditions shall be subject to the conditions that can meet the on-site use of the instrument.

2) Instrument: The error limit of the standard instrument used for calibration should be 1/3~1/10 of the error limit of the calibration meter.

3) Personnel: Calibration is different from verification. The person performing the calibration should undergo a valid assessment and obtain the corresponding qualification certificate. Only the certificate holder can issue a calibration certificate and a calibration report, and only such certificates and reports are recognized of.

For example, for pressure gauge calibration, you can find local measurement institutes or third-party calibration units, such as provincial and municipal metrology institutes or local third-party calibration agencies, etc...., the premise must be issued by the local metrology standards and the National Laboratory Accreditation Commission CNAS certificate
