surface Roughness tester

Brand Name	Landtek		Place of Origin	China
Model Number	SRT-6210

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.
