Accredited Calibration or Traceable Calibration?

The GRAS Accredited Calibration Laboratory is accredited by DANAK, the Danish Accreditation Fund. This accreditation is a quality label that proves that our calibration laboratory complies with the ISO 17025 standard for laboratories.

If your quality assurance programs demand it, or if you for other reasons need the enhanced confidence that comes with an internationally recognized quality label, a GRAS Accredited Calibration is the right choice.

Traceable Calibration

A GRAS Traceable Calibration is identical to the rigorous calibration that all GRAS microphones are subject to before leaving the factory. This calibration is traceable to Physikalisch-Technische Bundesanstalt (PTB), in Germany.

When you are confident that your needs are covered by a traceable calibration, a GRAS Traceable Calibration is the right choice.
