Coefficient of friction tester is designed and manufactured based on mechanical-electrical integration according to standards GB/T 17200, GB 10006, ISO 8295, ASTM D1894, and TAPPI T816. It is applicable in static and kinetic coefficient of friction test to plastic films, foils, paper, and other materials. By testing the coefficient of friction, users can control the quality technique index such as seal property of packages, the speed of packing machines and so on.
