Product Details


This instrument is compatible with four standards of site to measure surface roughness of various machinery-processed parts, calculate corresponding and 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 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 analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier.
The exclusive DSP processes and calculates and then outputs the measurement results on LCD.
