Portable Surface Roughness Tester - Qualisurf II-S

QualiSurf II surface roughness tester is suitable for the scientific labs, factory metrology rooms and working site. It can test the surface roughness of various machining components and allows for user selectable 45 roughness units in Ra, Rz etc. The testing results and surface profile can be stored in QualiSurf II unit and be output to PC.

Besides QualiSurf II, Qualitest also offers QualiSurf IIS which has an external transducer with extended connection cable. QualiSurf II S is suitable for measuring the surface roughness inside the pipes and tubes.
