The Roughness Tester PCE-RT-11

Roughness Tester PCE-RT 11 Roughness tester for accurate determination of roughness according to Ra, Rz, Rq and Rt / with piezoelectric probe / big OLED display with backlight
The Roughness Tester PCE-RT-11 is a portable measuring instrument for determination of surface roughness according to Ra, Rz, Rq and Rt in just one device. The small roughness tester is especially designed for fast measuring of roughness. The roughness (obsolete: throatiness) is a term of surface physics that describes unevenness of surface height. The roughness tester works according to the same piezoelectric micro probe principle like the highly accurate laboratory measuring instruments. The easy handling of the roughness tester as well as the high repetitive accuracy characterizes this device. After touching the button the piezoelectric micro probe of the roughness tester scans the surface within seconds and shows digitally, according to the preselected cut-off length, either the value Ra, Rz, Rq or Rt. If there are any questions about the Roughness Tester PCE-RT 11 have a look at the technical specification below or call: UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703.

Rz (average roughness) The average roughness Rz is the arithmetical mean out of the biggest single roughness depth of many abut sections of measurement.
Ra (arithmetical mean deviation) Ra is the generally acknowledged and internationally recognized roughness parameter. It is the arithmetical mean deviation with absolute values of profile deviations within sample area.
Rt (maximum roughness depth) The maximum roughness depth Rt is the distance between the highest and deepest point of the measuring area.
Rq (square average roughness value) Rq is the square medium value of all ordinate values within the single measuring area l. Rq corresponds to the term RMS (Root Mean Square).
