1.Application

Computer Control Electro-Hydraulic Servo Tensile Testing Equipment聽is equipped with computer, printer, and general test software, to give an accurate determination of metal the material tensile strength, yield strength, the provisions of non-proportional extension strength, elongation, elastic modulus mechanical properties. Test results can print (force – displacement, force – deformation, stress – displacement, stress – deformation, force – time distortion – time) six kinds of curves and related test data, with the software self-test function that can self-diagnose problems. It is ideal testing equipment for the industrial and mining enterprises, scientific research units, universities, engineering quality supervision station. They are perfect testing instrument project quality testing section, universities and colleges, research institution and industrial and mining.
