This instrument is compatible with four standards of

site to measure surface roughness of various

machinery-processed parts, calculate corresponding

and clearly display all measurement parameter.

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

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.

* Multiple parameter measurement: Ra, Rz, Rq, Rt

* Highly sophisticated inductance sensor

* Four wave filtering methods : RC, PC-RC,

   GAUSS and D-P

* Built-in lithium ion chargeable battery and control

   circuit with high capacity

* Small in size, light in weight and easy to use

* Can communicate with PC computer for statistics,

   print and analyz by the optional cable and the

   software for RS232C interface.

*Manual or automatic shut down. The tester can be 

   switched off  by pressing  the Power key at any time.

   On the other hand, the tester will power itself off

   about 5 minutes after the last  key operation.
