Surface Roughness Tester Cr 4032 - China

price: contact company for price

1.FEATURES This instrument is compatible with four standards of ISO,

DIN, ANSI and JIS and is widely used in production site to measure

surface roughness of various machinery-processed parts, calculate

corresponding parameters according to selected measuring conditions

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 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.
