Surface Roughness Gauge: RTD-210
Separate Stylus Profilometer
The RTD-210 by Starr Instruments is an advanced surface roughness tester that provides the user with comprehensive testing capabilities. It is designed to allow testing on almost any surface, including difficult to access samples sich as internal bore and curved surfaces.
The separate motor drive unit is attached on a 1 metre long USB fly-lead. This is to allow user measurement of the roughness of both internal or external bores on small diameter pipe or tube, stepped gears, o-ring grooves and recessed notches.
The RTD-210 uses a highly sensitive, diamond-tipped stylus sensor that accurately traces the surface, measuring the vertical deviations from the centre line. It is able to display the results in many parameters including Ra, Rz, Rq, Rt, Rp, Rv, Rsk, Rmr to name a few. The results are clearly shown on the high resolution, colour touch-screen LCD; including the waveform trace of the test sample and automatic conversion to another parameter.
Results can be saved to the 100 record internal memory and managed with software or downloaded via Bluetooth to a free Android APP. (no iOS version available at this time).
