RT120 Profilometry Roughness Tester

Surface Roughness

RT120 was conceived from the need to characterise roughness and micro-profiles on pieces, even complex ones, using one device, thanks to the RT120 “all-in-one” logic and Profile Studio analysis software. Profile Studio software was developed to be extremely user friendly and easy to use by the operator; all functions required for the characterization of the profile and roughness are available in the right toolbar and divided into categories, each one featuring a different colour. New dimensions and roughness analyses can be input on the same profile and displayed on the same screen, in order to allow the operator to carry out a complete analysis of the piece, with one single measurement. Thanks to the self-comparing function, it is possible to reconstruct all dimensions and dimensional tolerances of a reference profile on a new profile, thus saving a considerable amount of time for the check in series. The roughness parameters are elaborated according to the most recent standards like ISO 4287, ISO 13565-1 and -2, ISO 12085, VDA 2007 for a total of 70 parameters calculated.
