Precision roughness tester TR 200

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.
