The COF Tester is precision laboratory testing equipment designed to measure static and kinetic coefficients of friction on flat material surfaces. It features high-precision load cells and stepper motor drive systems, equipped with touch screen operation, real-time friction curve display, automatic data calculation, storage, and report output capabilities.
The instrument operates with exceptional stability and low system error. Each test cycle provides both static and kinetic COF values. It supports data export and external printing, making it ideal for incoming inspection, production quality control, and material R&D laboratories.
