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.
