Roughness and contour measurement at a measuring station with MarSurf XCR 20
The combined measuring station allows both surface roughness and
contour measurements to be performed at a single measuring station.
Depending on the measuring task, either the GD 25 drive unit for surface roughness measurements or the PCV drive unit for contour measurements can be activated.
Both measuring systems are fixed to the measuring stand by means of a combi holder.
