SRT-6100 Digital Surface Roughness Tester Multiple Parameter Measurement Ra Rz Metal Roughness Meter Graigar the thickness of rebar andBrand: Graigar Features: Be compatible with four standards of ISO, DIN, ANSI and JIS. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism inside the tester. The sensor gets the surface roughness by the sharp built in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate
