Calibration Weights

Balances or scales should always be checked with reference weights that you can rely on and trust. Our accredited mass laboratories clean, calibrate and adjust your weights, then document the results in calibration certificates with details of conventional mass correction, uncertainty and traceability information according to ISO/IEC 17025.

Our unmatched global network of 14 calibration laboratories across Europe, the Americas and Asia guarantee fast and cost-effective mass calibration.

Our metrology staff are passionate about their calibration work, to ensure you receive first class service as well as continuously improved results.

The combination of robotic technology and world-class mass comparators delivers proven reliability and outstanding measurement performance.

Scopes range from OIML E to M classes and ASTM classes. For heavy-duty weights, services cover all steps from re-painting to calibration, even for weights up to 5 t.

Weights up to 50 kg undergo treatment in a total of six separate customized baths. Each weight is cleaned and stabilized in a fully automated process prior to calibration to ensure uniform surface conditions.
