Traceable Calibration

All microphones manufactured by G.R.A.S. are by default given a Traceable Calibration, which we also offer as an after-sales service.

Accredited Calibration

Microphones and microphone sets, including flush-mount and surface-mount microphone sets, are eligible for Accredited Calibration, either as part of the initial delivery or as an after-sales service. For all other products, contact your local G.R.A.S. partner.
