Standard Sensor of Surface Roughness Tester

Small hole sensor KS100 is the standard sensor for KR220 for flat surface, for shaft along axial direction, in holes of diameter greater than 5mm and a depth less than15mm. Except for flat surface, we recommend the tester combination with platform KA520, KA620, if the sample is flat but is too small to place the compete device , still a suitable height adaptor is required.
