manufacture, roughness testing machine manufacture
Features:
Surface roughness tester SRT6210 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
