Factory-Calibration

Dokumente einer Werkskalibrierung

Our calibration capabilities are not limited to the areas of accreditation. We strive to constantly expand our capabilities, including research and development of methods, procedures and fundamentals of gas physics.

The accredited quantities such as volume and mass flow or volume and mass of air and gases (as well as all others) are available for a broader measuring range in the form of a factory calibration. These areas have not yet been reviewed by a DAkkS auditor, but have already completed all TetraTec internal verifications. The non-accredited areas and procedures are generally strongly orientated towards the accredited processes and are in no way inferior to them in terms of quality. So if you develop a need for calibrations with very small gas flows, high pressures or using special pure or mixed gases, the solutions of our calibration laboratory are also available to you there.
