Pre-calibration Services
If needed, a pre-calibration of your GRAS equipment can be performed. This is useful when the user wants to document the equipment´s performance before service or repair of the unit. The pre-calibration data is valuable when the user suspects that there might be something wrong with the equipment which has already been used for measurements. Finally, this data can be used for making post-measurement corrections of the results. After service or repair of the unit, a traceable or accredited calibration must be made.
Calibration at regular intervals is a way to safeguard the quality of your measurements and to eliminate the costs caused by unreliable equipment. Also, it is a way to ensure that historical measurement data is valid and comparable.
Depending on the use, measurement environment, and internal quality control programs, we recommend that microphones are calibrated at a dedicated calibration laboratory at least once a year.
We endorse our ISO/IEC 17025:2005 Accredited Calibration Laboratory in Denmark and the GRAS Microphone Calibration Centers located in Asia, Europe and North America.
