Features
The surfaces roughness tester is a small handheld instrument, for shop
floor use and mobile measure, it operation simple, function overall,
measure fast, accuracy stability, take convenience. This tester applies to
production site and can be used to measure surface roughness of various
machinery-processed parts. This tester is capable of evaluating surface
textures with a variety of parameters according to various international
standard. The measurement results are displayed digital/graphically on the
color graphic LCD display, And output to the printer.

Measurement principle
When measuring roughness of part surface, the pickup is placed on
the surface of the part and
then tracing the surface at constant rate. The pickup acquires the
surface roughness by the sharp stylus in pickup. The roughness
causes displacement of pickup which results in change of inductive
value of induction coils thus generate analogue signal which is in
proportion to surface roughness at output end of phase-sensitive
rectifier. This signal enters data collection system after amplification
and level conversion. After that, those collected data are processed
with digital filtering and parameter calculation by DSP chip and the
measuring result can be read on LCD, printed through printer and
communicated with PC.
