R6000 Surface Roughness Tester


The new PTc R6000 surface roughness tester is designed with an integrated micro-processor,  sensor and OLED display in one unit.  Push-button-selectable  roughness units of Ra,Rz, Rq and Rt.


The new PTc R6000 surface roughness tester features an advanced micro-processor and  a sensor integrated into one pocket-sized unit for performing data acquisition, data processing and display of all test measurements. This instrument has an OLED display  and allows for push-button- selection of roughness units in Ra,Rz, Rq and Rt.

The R6000 measures the surface roughness of flat, round and sloping planes. Moreover, this new model is able to measure grooves and recesses up to 3.1 x 1.2 in (80 x 30 mm).
