Foil Surface Roughness Tester for Rolled Aluminium

Portable stylus profilometer measuring Ra and Rz of rolled foil and sheet surfaces. Used for roll quality control and laminating adhesion work. Surface values help control rolling quality and adhesion of coating or adhesive.

Specification

A diamond stylus traverses the foil on a flat support and the vertical movement is converted to Ra, Rz and Rmax values. Cut-off lengths of 0.25, 0.8 and 2.5 mm suit rolled surfaces.
