Precision instrument measures damage to surfaces not classified as ordinary wear.
Using precision 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.
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.
Test a wide range of products.
