Digital Surface Roughness Profilometer Ra, Rz, Rq, Rt

SKU: SRT-6210
  • Model # 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 parameters.

    • 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 Profilometer can be switched off by pressing  the Power key at any time. On the other hand, the Profilometer will power itself off about 5 minutes after the last  key operation.

    • The Profilometer can memorize 7 groups of measurement results and measuring conditions for later use or download to PC.

    • Metric /Imperial Conversion
