SSB-300BB electro-hydraulic servo universal testing machine is a high-precision material testing equipment that uses hydraulic power source drive, electro-hydraulic servo control technology, computer data acquisition and processing, and can realize closed-loop control and automatic detection. It is controlled by test host and oil source. (hydraulic power source), measurement and control system, test equipment consists of four parts, the maximum test force is 300kN, and the test machine accuracy level is better than level 1.

SSB-300B electro-hydraulic servo universal testing machine is a versatile product, which can meet the national standard test of metal tensile test regulations, and can also stretch different materials or products according to other standards. , compression, bending, shearing and other types of tests, can obtain the tensile strength, yield strength, specified non-proportional extension strength, elastic modulus and other performance indicators of the measured materials, can achieve equal rate loading, iso- rate deformation, Closed-loop control such as equal-rate displacement and constant-rate strain can be used to verify the process qualification of materials or products.
