LFY-817 Sliding Friction Coefficient Tester

Main purpose/Use 
The sliding friction coefficient tester accurately measures the static and dynamic friction coefficients between the sheet material 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 friction coefficient and the dynamic friction coefficient of the sample. 
(2) Computer control, automatic display of test data, results and curves. 
(3) Human-computer dialogue interface, Windows operating system. 
(4) The driving mechanism is free from vibration, enabling the two test surfaces to move relative to each other at a speed of (50 ± 2) cm/min. 
(5) The total error of the entire force measurement system is less than ±2%, and the transformation time T does not exceed 0.5 seconds. 
(6) The force direction of the driving mechanism is parallel to the frictional sliding direction.
