Best Sale Surface Roughness Tester KR220 is the best portable surface roughness tester,Website:http://www.kairda-group.com,with 16 roughness parameters,0.001 resolution,suitable for all kinds factory surface roughness testing.
Applications
Measurable workpiece range: plane, cylindrical surface, cone, bore, groove, surface, etc. (special surface to be equipped with a sensor for measurement).
Working Principle
When measuring the surface roughness, the sensor slides along the straight line at a constant velocity along the measured surface. The stylus touches the measured surface to generate displacement. The data is collected by the filter. The DSP calculates the output and displays the measurement result.
