The MarSurf M 300 (6910401) is an advanced and easy to use surface roughness gage/profilometer that is built on the M series platform. The unit boasts a Bluetooth interface between the evaluation unit and the drive unit.  This makes positioning of the unit for assorted measuring applications very easy!  A large, illuminated color display to read the parameters and the profiles allow viewing your measuring results in a poorly lit environment.

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