Product Information:

The high-low temperature electronic universal testing machine is suitable for evaluating the mechanical properties of both metallic and non-metallic materials, including tensile, compression, ring stiffness, flattening, bending, shear, tear, peel, and puncture tests. It can perform automatically controlled tests under constant rate of loading, constant rate of deformation, and constant crosshead speed, and is capable of low-cycle load, deformation cycle, and displacement cycle testing. Key material properties such as elongation, tensile strength, bending modulus, elastic modulus, yield strength, net energy, rebound energy, and total energy can be measured.

Data processing and analysis are conducted via PC, with test results automatically saved. After the test, curves can be reloaded to reproduce the test process, and can be compared or magnified as needed. The testing software, compatible with Windows and VISIT platforms, provides powerful data and graphical processing capabilities, and can instantly generate complete test reports and test curves.
