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).

Our range of services at factory calibration:

Measurement Quantity	Measurement Range	Calibration Standard	Trace- ability
Leackage (Air) Volume Flow (Air) On-site Mass Flow (Air) On-site	0,6 ml/h up to 60 ml/h 60 ml/h up to 10.000 m³/h 60 ml/h up to 4.700 m³/h 72 mg/h up to 12.000 kg/h 72 mg/h up to 5.640 kg/h	PVTt procedure Crit. nozzles, gas meter, LFE Gas meter, LFE Crit. nozzles, gas meter, LFE Gas meter, LFE	DAkkS
Flow Generation In house (Air) On-Site (Air)	bis 100 Nm³/h compressed air (8 bar) up to 500 / 2000 / 10.000 m³/h vacuum (-600 / -300 / -80 mbar) Medium supply must be provided by customer.

Positive pressure Negative pressure	0 up to 70 bar 0 up to -1 bar	Piston manometer, El. pressure sensor	DAkkS
Temperature	0 up to 90 °C	Resistance thermometer, water bath	DAkkS
Relative humidity	0 up to 95 % r.F.	Dew point mirror, El. humidity sensor	DAkkS
Direct voltage Direct current DC Resistance	0 up to 60 V 0 up to 3 A 0 up to 12 M Ohm	System Multimeter, El. signal meter, Resistance meter, fixed resistor	DAkkS

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.
