Surface Roughness Tester Parameter RA, RQ, RZ, RT

The roughness tester also referred to roughness meter or roughness gauge to determine the roughness of the object. it is quickly and easily to get the measuring result. KR110 surface roughness tester is the basic model of our surface roughness tester series mostly used to measure flat surface, it also can be used to measure shaft and work with fixture to make it stable. you can also take measurements in groove that is larger than 80*30 mm.
the probe assembly and main unit are integrated, the slider to protect the stylus tip during non-use.
The surface roughness tester parameters include: Ra, Rz, Rq, Rt
