calibration certificates

ISO calibration certificates (factory calibration certificates) are issued at GHM Greisinger according to the same standards as DAkkS calibration certificates, but without the expense for external evaluation, so these certificates can be issued at a reasonable price. In addition, there are measurement parameters for which no accreditation can take place in DAkkS-DKD. In such cases, the ISO calibration is an important alternative. ISO calibration certificates are issued with measurement standards which are subject to regular inspection of measuring and testing equipment, thus ensuring the traceability of the measurement standards used in the process. The calibration includes, if applicable, adjustment of the measurement device (only with Greisinger devices). The listed ISO calibration certificates are available for handheld instruments. ISO calibration certificates can also be issued for measuring transducers and combinations of display instruments and sensors/transducers. Test reports are included in the scope of supply of some devices. Calibration certificates have to be ordered seperately.


DAkkS calibration certificates

DAkkS calibration certificates are issued for very high-quality calibrations and for calibration of reference devices or when stipulated by standards and regulations. DAkkS-DKD calibration certificates are issued with reference devices which must be traceable through a chain to the Laboratories of the German Calibration Service. DAkkS-DKD calibration certificates can only be issued by the calibration laboratories accredited in accordance with the standard DIN EN ISO 17025.

With recurring external certification and re-accreditation, it is ensured that a consistently high quality of calibration is maintained. These cost-intensive and personnel-intensive measures entail higher prices, but ensure the necessary reliability of the measurement results. We offer the DAkkS calibration certificates listed below for handheld measuring devices. DAkkS calibration certificates can also be issued for measuring transducers and combinations of display unit and sensors/transducers.
