What is Coefficient of Friction Tester?

The GT-N35 Paper Friction Coefficient Tester is It is used to measure the dynamic and static coefficients of plastic film and leather, rubber, paper and cardboard, woven bags, fabric styles, metal composite belts for communication cables and optical cables, pipe belts, wood, coatings, films, wipers, shoe materials, tires and other materials when sliding.

Applicable Standards of Coefficient of Friction Tester GT-N35

The working principle determines the accuracy and stability of the friction coefficient test. The  COF tester GT-N35 adopts a mechanical and electronic combined test mode, and the operation process is easy to understand.

One of the two tested materials is laid flat on the test table, and the other is fixed on a slider with specified weight.

The two test surfaces are attached closely under certain contact pressure.

The system drives the two surfaces to produce relative sliding movement, and records the friction force generated during the process in real time.

The coefficient of friction is calculated by dividing the measured friction force by the gravity of the slider.

The performance features of the plastic film testing equipment GT-N35 are important for accurate and efficient friction coefficient testing.

Stroke Control: Slider stroke can be preset with a wide adjustment range, and dynamic & static friction coefficients are displayed digitally in real time.

Driven by precision differential motor, with smoother transmission, lower noise and better repeatability of test results.

65 million color TFT LCD screen with real-time curve display; equipped with high-speed micro printer, which supports fast and low-noise printing, easy paper roll replacement without ribbon.

Adopts slider running device and sensor fixed-point force measurement mode, which effectively avoids sensor errors caused by motion vibration.

Supports real-time digital display of dynamic and static friction coefficients; slider stroke is adjustable in a wide range, and multiple test modes are optional.
