150J 300J bolt screw Charpy pendulum shock impact toughness tester

The manual semi-automatic impact tester is used to determine the resistance of metal materials to impact under dynamic load, and to judge the quality of the material under dynamic load.

The principle machine of the testing machine has single supporting column structure, cantilever type pendulum hanging mode, the pendulum body is U-shaped. The impact cutter is installed and fixed by screws and is convenient and easy to be replaced. The specimen is supported via simply by supported beam. Safety guard pin is arranged on the principle machine which is also provided with safety guard net.
