The accreditation certifies the expertise, independence and performance of our calibration laboratory. MMF has stood for quality in vibration measurement technology for more than 60 years. It is important to us that the quality of our calibration service is verified by third parties. Our customers can trust that we work according to scientifically recognized and objective methods and achieve comparable and reproducible results. We now offer the option of accredited calibration for our products from a single source. Products from other manufacturers can also be calibrated. For current and detailed information on the specific scope of the accreditation, i.e. on the accredited measured variables, possible measuring ranges and measurement uncertainties, please refer to the certificate appendix D-K-21664-01-00, which is available for download.

Metra offers factory calibrations for vibration transducers, instruments and measuring chains consisting of sensor and amplifier. In this case the calibration is the responsibility of the performing calibration lab. Factory calibration service is not accredited and therefore not covered by the EA MLA (European co-operation for Accreditation Multilateral Agreement), nor is it traceable. Factory calibration includes the issuance of a non-accredited calibration report on which the reference standards and the measured values are listed.
