TR 200 Features Scope of Delivery
TR 200
The TR 200 is a precision surface roughness tester with interchangeable stylus and good for use in manufacturing workshops and laboratories alike.
Besides numerical values the graphic display shows the roughness profile and material ratio curve. The analysis of readings helps compute 13 different roughness parameters (Ra, Rz, Ry, Rq, Rt, Rp, Rmax, Rm, R3z, S, Sm, Sk, Tp).
Menu-driven operation in German, English, French, Italian, Dutch and Spanish.
The polished diamond probe tip has a radius of 5 µm; a special 2 µm stylus tip is (also) available.

Application
Roughness measurement on hard objects (steel, glass etc.).


The portable RT-10 PLUS palmtop roughness tester, permits the  evaluation of the most important roughness parameters directly on the production site, offering, in a compact package, the advantages of being easy to carry, simple to use and reliability of measurement.

Designed for use on the shop floor, it is shielded against external agents by a special protective membrane. It may measure in difficult positions, including when held in the hand, in the vertical traverse position.


The RT10 Plus (code 1.101) roughness tester features a plug-in connector that allows to interchange the pick-up, thus being able to take measurements on all types of surfaces, by simply mounting the most suitable pick-up.

RT10G

RT10G roughness tester was born from the success obtained by RT10; easy to handle and reliable like the basic version, it also carries out advanced analyses typical of a laboratory instrument.

In addition to 31 roughness parameters calculated, RT10G displays the graphs of the roughness profile, primary profile, bearing capacity curves, distribution of ordinates, and allows to set tolerances on single parameters and personalize prints. RT10G uses new generation electronics with 0.001 µm resolution that ensure always reliable results and displays them in a user-friendly fashion, thanks to the internal icon menus taken from modern Smartphones.

RT120  Laboratory Profilometer-roughness tester

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.
