Roughness Tester



Applications:
● This multi-parameter tester designed to measure 4 parameters (Ra, Rz, Rq, Rt) using the built-in diamond pin probe. This tester is
widely used in production sites to measure surface roughness of various machinery-processed parts and calculate corresponding
parameters according to selected measuring conditions and clearly display all measurement parameters in Metric or Imperial. It
also has 4 wave filtering methods (RC, PC-RC, GAUSS & D-P) and memorize 7 groups of measurement results & conditions for
use at a later time.
● Widely used in production sites, laboratories and workshops etc.


Product description:
● Uses advanced computer technology, in line with the standards such as GB/T 6062, ISO, DIN, ANSI and JIS etc.
● 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.
