DAkkS Calibration Laboratory

MBW Calibration GmbH in Fellbach operates a calibration laboratory (D-K-21411-01) for humidity and temperature accredited by the German Accreditation Body (DAkkS) according to DIN EN ISO/IEC 17025. The measurement uncertainties for our calibration services are amongst the lowest worldwide. We offer short lead times for all types of hygrometers.

Our calibration laboratory in Germany uses calibration stations based on primary realization for the lowest uncertainties, and also commercial humidity generators for calibration by comparison. SI traceability is from MBW dew point mirror transfer standards, SPRT’s and the triple point of water. Through the ILAC Mutual Recognition Arrangement (ILAC MRA) our calibration certificates are internationally recognized and suitable for evidence of traceability in all ILAC MRA signatory countries.
