Calibration of vacuum gauges at The National Laboratory
The pressure and vacuum National Laboratory performs calibrations of all types of vacuum gauges. Calibration at the National Laboratory always guarantees the highest possible traceability in the measurements performed.
Purpose
The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competens and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden.
A calibration performed at a national laboratory fullfils all typical traceability and accreditation requirements that commonly exist in industry and society at large.
Method
The vacuum gauge is connected to the national Laboratory's standards and the calibration is performed at agreed upon pressure levels. Calibration of vacuum meters always takes place at increasing pressures. The National Laboratory performs calibrations of vacuum gauges from 5·10-6 Pa and upward.
Since the National Laboratory is the highest calibration body in Sweden, calibrations are performed here with the highest possible traceability.
The pressure media used for calibration of vacuum gauges at the National Laboratory site is nitrogen gas.
Deliveries
The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.
