  • 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.
