Calibration laboratories

Mahr runs laboratories for various instruments and sizes in the field of length metrology. These ensure high dimensional accuracy and very low measuring uncertainties. In principle, all measuring equipment can be calibrated. Specific core skills are offered for the following calibration services:

• Setting rings* / ring gages*
• Setting plug gages* / plug gages*
• Setting disks*
• Setting masters
• Setting standards for internal micrometers
• Setting standards for external micrometers*
• Dial comparators*
• Lever-type test indicators*
• Geometry and roughness standards*
• Thread plug gages, thread ring gages
• Internal and external measuring instruments
• Inductive measuring instruments and probes*
• Calibration balls
• Tall cylinder squares*
• Rulers
• Micrometers*
• Calipers*
• Dial indicators*
• Measuring anvils
• Measuring tables and V-blocks
• Angularity measuring instruments
• Roughness measuring instruments
• Roughness standards*
• Snap gages
• Radius, thread-form and sensor gages
• Standard cylinder squares*
• Parallel gage blocks* made of steel, ceramic, hardened metal, including special forms and special sizes
• Parallel pieces
• Optical flats
• Pin gages*
• Flats
• Roundness standard*
• Depth setting standards*
• Magnification standards* (flicks)
• Spline gages
• Angle standards
• Bevel protractors

* Calibrations with officially recognized calibration certificates to national and international standards e.g. NIST (National Institute of Standards and Technology), and DKD (German Calibration Service). NIST is the national standards institute in the United States.

The DKD (German Calibration Service) is a signatory of the multilateral agreement of the European cooperation for Accreditation (EA) and the International Laboratory Accreditation Cooperation (ILAC) for mutual recognition of calibration certificates.

Your Mahr contact partner will provide you with information on national and international recognition e.g. as part of the multi-lateral agreement www.european-accreditation.org/.
