It is suitable for the packaging industry, the paper-making industry, film manufacturers, packaging material testing institutions, etc. to measure the static friction coefficient and dynamic friction coefficient during the sliding of materials such as plastic films, rubbers, papers, paperboard, woven bags, woods, coatings, etc. By determining the magnitude of the friction coefficient, the smoothness, the difficulty of opening, and the uniformity can be judged, so as to correctly guide production and control and adjust the production process.

Cut the sample into two pieces. Place one piece on the workbench and clamp it with the sample holder. Wrap the other piece around the slider. Then, place the slider on the hanging hole of the sensor. Make the sample move under the gravity applied to the slider, that is, make the two test surfaces move relatively. The force signal measured by the sensor is amplified by the integrator and sent to the recorder. At the same time, the dynamic friction coefficient and the static friction coefficient are recorded respectively.

1.Stable performance and accurate test results.

2.Simple operation and thermal printing of test reports.

3.Longer service life and more perfect performance.

4.5-inch touch screen display for convenient operation.

5.Capable of saving 10 groups of data and printing them.

6.Password is required for calibration to prevent accidental modification.
