The digital display electronic universal testing machine is mainly used to test the tensile and compressive strength of various materials and the ring stiffness of plastic pipes. In tensile tests, it measures the material's maximum tensile load, tensile strength, elongation, and elongation rate. In compressive tests, it measures the material's bearing pressure, tensile strength, and maximum compressive deformation. After the test, the main controller automatically calculates the test parameters based on the test conditions set at the start of the test and displays the corresponding results. Each test parameter can be printed after the test or saved in the controller for later retrieval and display.
