LFY-817A Thin Sheet Friction Coefficient Tester

Main application
The sheet friction coefficient tester accurately measures the static and dynamic friction coefficients between sheet materials and the friction medium in dry, wet and oily conditions, and displays the curve of friction force changing over time in real time.
Instrument features
1. The system can simultaneously measure the static and dynamic friction coefficients of the sample.
2. Computer control, automatic display of test data, results and curves.
3. Human-machine dialogue interface, Windows operating system.
4. The driving mechanism has no vibration, allowing the two test surfaces to move relative to each other at a speed of (150 ± 30) mm/min.
5. The total error of the force measurement system is less than ±2%, and the transformation time T does not exceed 0.5s.
6. The force application direction of the driving mechanism is parallel to the friction sliding direction.
