PCE Instruments Roughness tester PCE-RT 11

(This text is machine translated) Roughness tester PCE-RT 11 The roughness tester is a handheld measuring instrument for determining surface roughness according to Ra, Rz, Rq and Rt. The compact roughness tester has been specially developed for the rapid measurement of roughness. The roughness is a term in surface physics that refers to the unevenness in the height of the surface. The measuring device works according to the same piezoelectric micro switch principle as laboratory instruments with high precision. The easy operation of the roughness tester, as well as the high repetition accuracy, make the roughness tester an extraordinary instrument. After pressing the button, the roughness meter scans the surface in a few seconds and immediately displays the value in Ra, Rz, Rq or Rt according to the pre-set wavelength limit (cut-off length). Technical specifications Roughness parameter: Ra, Rz, Rq, Rt Precision: ±15 % Repeatability: <12 % Measuring range Rz, Rt: 0.1 ... 50 µm Measuring range Ra, Rq : 0.05 ...
