Laboratory set up according to ISO 17025 calibrates dial gage testers and dial indicator testers.

Mahr in Göttingen operates a DKD lab for surface, form and contour standards. This lab has now been also accredited for vertical length testing units, such as Optimar 100! The audit for the extension of the accreditation took place in 2009 by auditors of the Physikalisch-Technischen Bundesanstalt. The DIN EN ISO 71025 was completely fulfilled and the extension to the calibration of dial gage testers and dial indicator testers was confirmed.
