Products & Services 

The world of measurement in manufacturing companies is changing rapidly: The workpieces are smaller, measurements must be made close to production, more quickly and with increasingly smaller tolerances and at the same time more cost-efficiently.

Mahr offers solutions in dimensional production metrology for the challenges of the present and the future.
A few examples: The highest national calibration laboratories in China use the "Precimar 828 CiM" from Mahr – the world’s most precise length measuring machine.
With the measuring unit "MarSurf PS 10" in a portable phone format, Mahr responded to the challenge of mobile testing the surface large workpieces.

Mahr takes the step into optical metrology with the combined 3D measuring system comprising a confocal microscope and white light interferometer "MarSurf CWM 100” with sub-nanometer resolution.
Since it was founded more than 150 years ago, Mahr has firmly established itself in the field of production metrology: The measuring instruments are used in the automotive industry as well as in the machine tool industry, in plant engineering, precision engineering companies and research laboratories.

Mahr’s flexible MarShaft SCOPE 250 plus shaft measuring machine offers the right measuring solution for the fast, precise and fully automatic measurement of rotationally symmetrical workpieces in production
