Surface Roughness Tester , AR-132C , surface roughness , 2 parameters Ra Rz , Pocket Portable Surface Profile: The proper and effective preparation of a surface prior to coating is essential. Making sure that the correct roughness - or profile - has been generated is essential.

If the profile is too low, the adhesion of the coating to the surface will be reduced. Too high and there is the danger that the profile peaks will remain uncoated - allowing rust spots to occur.

How it works: 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 surfaceroughness at output end of phase-sensitive rectifier. The exclusive DSP processes and calculates and then outputs the measurement results on LCD.
