Mahr Federal M1 Perthometer      

The Basic Model for Entry Level Surface Finish Roughness Measurement

                This instrument serves for determining and documenting the most common parameters as per DIN EN ISO/AMSEprEN 10049 (Ra, Rz, Rmax and RPc) and according to the JIS Japanese standard (Rz, Ra).

With a minimum of keys, the Perthometer M1 is characterized by a multitude of function. An automatic function enables periodic and aperiodic profiles to be identified and the cutoff to be set according to standards without any prerious test measurement, such that unintentional non-standard measurements are excluded.

In mobile use, the measuring record can be output on the built-in thermal printer automatically or simly by pressing a key. Stationary operation offers the possibility of connecting the Perthometer directly to a PC via the serial interface.
