Multi Finger Scratch Mar Tester With A Pneumatically Driven - China

Multi Finger Scratch/Mar Tester uses tungsten carbide as a scratch to accurately detect surface damage caused by unconventional physical forms (such as scraping, grasping, planning etc).

It can be used to detect the wear resistance of plastic parts in automobile interior and exterior trim, and can also be used for the testing of hard material wear, paint, ink, soft metal, oil carpet and other materials.

The instrument includes a pneumatically driven, moveable sledge to which the test sample is mounted.

The sledge moves in a linear fashion, and is operated by a control knob for one or multiple pass testing.

An electronic timer displays the rate of speed, which can be controlled by reducing or increasing air pressure.

A gantry supports five independent splined-fingers, which provide a constant, vertical load on interchangeable scratch pins (1.0mm or 7.0mm diameter hemisphere).

The gantry system includes a handle to raise and lower the arms.

In addition, five support rests are incorporated to allow one or more arms to be moved to an upright, rest position such that the arm does not contact the specimen during testing.
