'A step ahead!'- with MarSurf M 300

NEW: cable-free connection between evaluation unit and drive unit!

The MarSurf M 300 was developed based on the well-proven class of M-units from Mahr.

The Bluetooth interface between evaluation unit and drive unit is unique. 

This means for you: working even more flexibly without cable connection  

A large, illuminated color display to read the parameters and the profiles so that you can:
-read the correct results in a poorly lit atmosphere!

The MarSurf M 300 not only meets the requirements for determination and documentation of selected parameters, but also makes most of the parameters and characteristic curves stipulated in DIN/
ISO/JIS available for the evaluation of the profile assessed.

Moreover, the MarSurf M 300 offers an integrated memory for up to 40,000 results or 30 profiles, as well as the functions of tolerance monitoring, vertical scale selection and the setting of unsymmetric intersection lines for peak count calculation.

     
Features
  • First portable roughness measuring unit with the option of wireless (Bluetooth) connection between the evaluation unit and drive unit
