Factory Calibration

Our calibration laboratory offers factory calibrations for all types of flow meters, as well as for the measured variables of pressure, temperature and humidity. We can provide you with factory calibrations both at our calibration laboratory as well as at your own premises.


The calibrations are subject to the recalibration and traceability requirements of DIN EN ISO 9001 and always ensue from a comparison with measuring equipment which has been regularly recalibrated in an accredited DAkkS calibration laboratory or at the Federal Institute of Technical Physics (PTB).

The flow quantities at on-site calibrations can now beginning with 16.06.2017 also be certified by a DAkkS calibration certificate.

For the best possible measurement uncertainties (MU) see annex to the DAkkS accreditation certificate or on request. Depending on the on-site calibration conditions in temperature, pressure and humidity though has to be added a MU adder.

Other gases than air on request! In house are more than 12 pure gases and gas mixtures permanently available.
