The small electronic roughness tester SurTest is designed for quick and accurate measurements. The gauge is suitable for use on the production floor as well as for inspection departments and quality control.
Performance features
- Selection of cut-off lengths
- Micro stylus
- small, handy gauge fits in every pocket
SurTest is simply placed on the surface to be measured and the micro stylus scans the surface within only a few seconds. Depending on the preset cut-off length, the value is immediately displayed in Ra or Rz.
Rz = mean surface roughness
The mean surface roughness Rz is the arithmetical mean of the highest
single reading of several adjacent single measuring sections.
Ra = arithmetical average height
Ra is the generally acknowledged
roughness parameter which is internationally used.
