Surface roughness tester

During the measuring procedure the sensor moves linearly along the measured length. The probe moves accordingly to the profile on the surface. These movements are converted into electric signals which are amplified, filtered and converted into digital signals by an A/D converter. These signals are then refined in the main processor as Ra and Rz values ​​(or Rq and Rt metrics) and displayed on the screen.
