Function:
The 250J 500J dial display charpy pendulum impact strength toughness testing machine 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. It can meets GBT 229, GBT 3808, ISO 148-1, ISO 83, ASTM E23 etc

 Character:

1. 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.
2. You can realize rising pendulum, quitting pin, impact and release pendulum by pressing the control button. You need to put the specimen on the support by hand every time.
3. After finishing the impact, you can read the impact energy by pointer on the dial.
