Nor278 Referensljudkälla

Each unit is carefully assembled and individual tested. To enhance the level of quality and traceability of your measurements every unit is accredited calibrated by the Norsonic Calibration Laboratory (NCL) in accordance to ISO 6926:2016. This service is also offered for periodic re-calibration.

Norsonic Calibration Laboratory is an accredited laboratory to work in compliance with ISO/IEC 17025 in carrying out calibration of acoustical equipment for measuring noise (sound level meters, microphones, dosimeters and acoustical calibrators), accelerometers, tapping machines and reference sound sources. The  accreditation is recognized internationally through European and global multilateral agreements in more than 40 countries around the world made through the International Laboratory Accreditation Cooperation – ILAC. Thus the Norwegian Accrediting body has established that Norsonic calibrations are internationally accepted as being carried out in an accredited laboratory.
