The BEVS Automatic Scratch Tester is used to determine the scratch resistance of a single coating or a complex coating system. A tungsten carbide stylus is scraped across a coated surface. A variety of weights can be added above the stylus to adjust the force with which it scratches. Select a standard weight for your test protocol, or gradually increase the weight to determine the maximum load at which the coating resists scratching.

Watch a real-time graphic display of your scratch test, and easily see Pass/Fail results displayed.
