Digital tear strength testing machine

This machine is mainly suitable for testing the tensile, compression, bending, shearing, tearing, peeling, compression, bending and other mechanical properties of metal, non-metal and composite materials, including tensile strength, elongation, yield Strength, cold bending properties and other properties.

1. Automatic stop: After the sample is broken, the moving beam stops automatically;

2. Automatic shift: automatically switch to the appropriate range according to the size of the load to ensure the accuracy of the measurement data

3. Condition storage: The test control data and sample conditions can be made into modules, which facilitates the batch test;

4. Automatic speed change: the speed of the moving beam during the test can be changed automatically according to the preset program or manually;

5. Automatic calibration: the system can automatically realize the calibration of the indication accuracy;

6. Automatic save: After the test is over, the test data and curves are automatically saved;

7. Process realization: the test process, measurement, display and analysis are all completed by the microcomputer;

8. Batch test: for samples with the same parameters, it can be completed in sequence after one setting;

9. Display mode: data and curves are dynamically displayed with the test process;

10. Curve traversal: After the test is completed, the curve can be re-analyzed, and the test data corresponding to any point on the curve can be found with the mouse;

11. Curve selection: Stress-strain, force-displacement, force-time, displacement-time and other curves can be selected for display and printing as required;

12. Test report: the report can be prepared and printed according to the format required by the user;

13. Limit protection: it has two levels of program control and mechanical limit protection;

14. Overload protection: when the load exceeds 3-5% of the maximum value of each gear, it will automatically stop;

15. The test results are obtained in two modes, automatic and manual, and reports are automatically formed, which makes the data analysis process simple.
