Walcher Meßtechnik GmbH – the parent company of the
Halstrup-Walcher Group – has been accredited by the German calibration service DKD and Deutsche Akkreditierungsstelle GmbH (DAkkS) as a calibration laboratory in accordance with DIN EN ISO / IEC 17025 since 1999 for calibration of pressure measurements and since 2016 for flow rate calibrations. Its calibration services are available for all makes of equipment independently of the type and manufacturer. Our high precision test objects, used as references during calibration, are calibrated at regular intervals at the PTB and therefore traceable to the national standard.
DAkkS calibration should be performed at measurement points which are critical to the quality of the product or service. It follows a recognised, standardised procedure (e.g. in accordance with DKD-R 6-1) and the uncertainty of the calibration is stated. The DAkkS certificate is internationally recognised and documents seamless traceability to national standards.
ISO factory calibration is suitable for instruments used as auxiliary devices for measurement and development purposes, e.g. in management of reference materials in accordance with ISO 9001. In contrast to the DAkkS calibration, the ISO factory calibration does not state the measurement uncertainty. ISO factory calibrations are performed in our production laboratory using traceable references.
