Universal finger friction tester

The Universal Finger Friction Tester is designed to evaluate the friction, abrasion, and scratch resistance of materials and coatings under highly controlled conditions. Using a specialized test head with adjustable pressure, the device simulates mechanical and chemical wear on surfaces. Test parameters can be customized, including dry conditions or exposure to liquids such as sweat or emulsions.

Application

This tester is widely used for evaluating coatings, plastics, textiles, footwear soles, dental materials, and other surface-treated products. It is suitable for research and development, quality control, and product validation across industries including automotive, consumer goods, footwear, medical devices, and electronics. The device provides realistic simulation of wear mechanisms, ensuring accurate prediction of material performance in real-life conditions.
