SRT-6200 Surface Roughness Tester is widely used in production site to measure surface roughness of various machinery-processed specimens, and to calculate corresponding parameters according to selected measuring conditions and clearly display all measurement parameters. It is international qualified product, which is compatible with four standards of ISO, DIN, ANSI and JIS.

Measuring Principle：
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 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.
