SURFACE ROUGHNESS TESTER HSRT-621
This instrument is compatible with four standards of the site to measure surface roughness of various machinery processed parts, calculate corresponding and clearly display all measurement parameters. 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 with the sharp built-in probe. This roughness cause displacement of the probe which results in change of the inductive amount of induction coils so as to generate the analog signal, which is in proportion to the surface roughness at output end of the phase-sensitive rectifier. The exclusive DSP processes and then
outputs the measurement results on LCD
