More info

The advanced surface roughness gauge RTD-300 from Starr Instruments is designed to allow testing of more difficult to access work pieces and has superior data capabilities to be a comprehensive testing device.

The separate stylus housing allows for measuring the roughness of inside or outside of bores on small diameter pipe or tube, stepped gears, o-ring grooves and recessed notches.  Industry examples include measuring roughness of cylinder heads or brake discs in Automotive or Rail Tracks after refurbishment and maintenance. 

To measure roughness the RTD-300 uses a diamond tipped stylus that accurately traces the surface of the material by measuring the vertical deviations from a uniform centre line and is able to display the results under many parameters including Ra, Rz, Rq, Rp, Rv, Rsk, Rmr to name a few.  The results are displayed on the large, high resolution, colour LCD including the waveform trace of the surface and results can be saved to internal memory and managed with the optional software.
