Laboratory roughness tester ALPA LA350

  • Face Test 120 was conceived from the need to characterise roughness and micro-profiles on pieces, even complex ones, using one device, thanks to the Face Test 120 “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-sided toolbar and divided into categories each one with 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.
