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. Our technicians and engineers will gladly advise you in all roughness testers and all products in the field of measuring instruments, regulation and control and scales.

Delivery content of the Roughness Tester PCE-RT-11.

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).

Optional Equipment for the Roughness Tester PCE-RT 11

ISO calibration for companies that want to include the Roughness Tester PCE-RT 11 into their 
test equipment pool or for annual recalibration. The certificate according to ISO includes a 
laboratory calibration test certificate included with all measuring values and the listing of 
the owning company on the certificate.
