New metrology era with Mahr’s new Bluetooth product

Date: October 2010

Mahr's Bluetooth-enabled roughness measurement system ushers in a new era of surface metrology.


Capable of transmitting data wirelessly within a radius of four metres, the handheld measuring unit of Mahr’s new MarSurf M 300 surface roughness measuring system enables the user to access and probe difficult-to-reach surfaces on large workpieces or components – such as propellers or turbine blades.

With 35 analysable parameters the M 300 provides a measuring performance of near laboratory standard and its large measuring range of 350 μm (0.014 inch) is constructed in such a way that even sand blasted surfaces can be measured.

The MarSurf M 300 was developed based on the well-proven class of M-units from Mahr but the Bluetooth interface between evaluation unit and drive unit is unique. This gives even more flexibly without cable connection.

Other features include a large, illuminated colour display to read the parameters and the profiles so you can read the correct results even in poorly lit areas.

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, it 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.
