KR100 Surface Roughness Tester

KR100 Surface Roughness Tester is a pocket type surface roughness measuring instrument, it measures the roughness of various machining parts, including plane, slope, outer circle. 

This Surface Roughness Tester is mostly is used for measuring flat surface, or directly put it in the grooves greater than 80*30mm which larger than the machine bottom, it is more convenient to measure large object upside or down orientation compare to other model, surface roughness tester KR110, this model you can also be held to measure the roughness for cylinder along the axial direction when the cylinder is 20mm or more in diameter, or using a optional fixture to make the small shaft more stable.

 KR110 is the advanced model based on KR100 that is add 2 of parameter, currently they are totally same, this is the roughness tester can measure RA, Rq, Rz, RT.
