Surface Roughness Tester By Guangzhou Landtek Instruments Co. Ltd.

Our clients can avail from us an excellent quality range of Surface Roughness Testers, which are available with following features:-
Model:SRT-6210
This Surface Roughness Tester is compatible with four standards of 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 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.
