Surface Finish Testing

Test a wide range of products. The five-fingerђ scratch tester has been popular in the automotive industry for testing smooth or grained plastics commonly used in ornamentation or trim. Useful for quality control as well as material or product development, theMulti-Finger Scratch / Mar Tester is ideal for evaluating plastics, rigid organic materials, paints and coatings, soft metals, linoleum, plus many others. Design based on five-finger scratching device described in automotive specifications. Specimens are secured to a pneumatically driven platform. Five independent spline-shaft fingers with varying weights exert a constant, vertical load on the test specimen as it travels under
interchangeable scratch tips. Spline-shaft fingers are mounted on a rigid gantry platform. Support rests allow the operator to secure
individual shafts in a rest position, permitting the testing of non-
standard width samples. Precision instrument measures damage to surfaces not classified as ordinary wear. Using precision tungsten carbide tips, the Taber Multi-Finger
Scratch/Mar Tester is used to measure the susceptibility of material
surfaces to scratching, marring, gouging, and other similar physical
damage not classified as ordinary wear. >
