Surface Roughness Tester SRT-6210S


  • Be compatible with four standards of ISO, DIN, ANSI and JIS. 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 inside the tester. The sensor gets the surface roughness by the sharp built-in probe. This roughness causes displacement of the probe. The exclusive DSP processes, 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.
  • Small in size, light in weight and easy to use.
  • Manual or automatic shut down.
  • Can memorize 7 groups of measurement results and measuring conditions for later use or download to PC.
  • Metric /Imperial Conversion.
  • Use “USB data output” and “RS-232 data output” to connect with PC.
  • Provide “Bluetooth ™ data output” choice.
