TR200 Surface Roughness Tester


PTc’s versatile TR200 Surface Roughness Tester measures & displays graphical and digital data in 13 different parameters.

The versatile TR200 surface roughness tester can be fitted with  various styluses to enable measurement the roughness of different surface contours.  In addition to graphical display on a large LCD, results are expressed digitally in Ra, Rz, Ry, Rq (RMS), Rt, Rp, Rmax, Rm, R3z, S, Sm, Sk, tp.

Data transmission to a printer or a PC is accomplished thru the RS232 interface.


  • Measures roughness of metal and non-metal parts
  • Menu operation, digital display, multi-parameters
  • Graphical display on large LCD
  • Stylus position indicator
  • Auto cut-off
  • RS 232 interface to PC or printer
