The hydraulic universal testing machine is mainly used for testing metal materials such as smooth round steel bars, ribbed steel bars, straight steel bars, coiled steel bars, metal plates, metal bars, cables and ropes, castings and forgings, bolt fasteners, metal pipes, etc. , and non-metallic materials can be tested and researched on tensile tests, compression tests, bending tests, shear tests, etc., and other mechanical properties at room temperature. The testing machine is equipped with a computer, printer, electronic extensometer, photoelectric encoder and general testing software, which can accurately measure the tensile strength, tensile strength, yield strength, specified non-proportional elongation strength, elongation and elastic modulus of metal materials. Quantitative equality. Experimental results can be queried and printed (force-displacement, force-deformation, stress-time, stress-strain, force-time, deformation-time, force-displacement, displacement-time) eight kinds of curves and related experimental data, with The software self-test function can self-diagnose faults. Please refer to the software description for details. It is an ideal testing design for industrial and mining enterprises, scientific research units, colleges and universities, engineering quality supervision stations and other departments.
