  • Surface Roughness Tester 

     

     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.
