TESA Profil 2 MM set 06960100

2mm profile set

TESA Profil 2 mm is a full set of accessories that converts Rugosurf 90G into a profile gauge able to evaluate geometric part features within each measuring spam:

● X-axis = 50mm

● Z-axis = 2000µm



Using straight lines and regression arcs, the software calculates form errors as well as the centre distance of two heights or two bores. The results can than be exported in DXF=format for a further use.

The full set includes:      06930012

● Profil Studio test software

● SB2000 probe for profile measurement in the Z-axis (2000µm)

● Reference test block for profile calibration

● Cable for connecting Rugosurf 90G to computer
