- Mahr - MarSurf - PC-Based Roughness Measuring Units
Technical innovation and quality-oriented thinking are the core competencies of successful businesses.
Both competencies are not possible without metrology.
Measurement instruments verify research and development results and document product quality.
Without continuous advancement of metrology there would be no technical progress.
Mahr offers a wide range of measuring instruments to solve your specific measuring task. Convince yourself!

Combined measuring station allows both surface roughness and contour measurements to be performed at a single measuring station. Depending on the measuring task, either the GD 25 drive unit for surface roughness measurements or the PCV drive unit for contour measurements can be activated.
The two measuring systems are fixed to the measuring stand by means of a combi holder.

Mahr replace with the MarSurf UD 130 the successful MarSurf UD 120 and closed the gap between the high end solution MarSurf LD 130/LD 260 and the standard combination measuring station MarSurf XCR 20 with two drive units.
The technical specification of the MarSurf UD 130 is far superior to that of the MarSurf UD 120: in particular, the measuring and positioning speeds have reduced the measuring time for each workpiece.

The PC-based instrument delivers all common surface parameters and profiles in accordance with international standards, both in the measuring room and in production. The powerful MarSurf XR 20 combines decades of experience in surface metrology with innovative technology, easy-to-read icons and user-friendly operator assistance.
A sampling length of up to 120 mm is possible in conjunction with the GD 120 drive unit.
In addition to surface roughness evaluations, profile and waviness evaluations can also be performed in this way.
The new MarSurf CD series from Mahr sets new standards when it comes to contour testing. With the new MarSurf CD series, manufacturing companies are entering a new dimension in order to reliably secure and improve the manufacturing quality of workpieces in the measuring room or close to production.
The new measuring station concept combines speed, reliability and flexibility. The aim is to increase the profitability of the system for your company.
Innovative technologies:
Due to the combination of the measurement and evaluation system with the CD 120 feed unit, you can perform contour measurements within a measurement area up to 120 mm in length and 50 mm in height.
Mahr offers a wide range of measuring instruments to solve your specific measuring task. Mahr is an application specialist in the field of production metrology, which solves the metrological tasks and is the contact partner for all questions related to quality.
