Model : SRT-6210
FEATURES
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
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 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 rechargeable battery and control
circuit with high capacity
* Small in size, light in weight and easy to use
* Can communicate with PC computer for statistics,
printing and analyzing 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.
* The tester can memorize 7 groups of measurement
results and measuring conditions for later use or
download to PC.
* Metric /Imperial Conversion
