The Taber® Multi-finger Scratch/Mar Tester Model 710 measures the relative resistance or susceptibility of a material surface to scratching, marring, gouging, scraping, engraving and other similar physical damage. The specimen is mounted on a moveable platform. Operated by a control knob for single or multiple pass testing, this platform moves in a linear direction.
A gantry supports five independent splined-fingers. This provides a constant, vertical load on interchangeable scratch tips. The gantry system has a handle to raise and lower the arms. Five support rests are also integrated to allow one or more arms to be moved to an upright, rest position. On the top of each arm finger are individual weights of varying loads which exert a standard force on the surface of the test material.
