300J manual pointer display metal chapry impact testing machine

The EJB-300 manual semi-automatic metal charpy impact 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.

 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.

Character:

1. You need to control rising pendulum, quitting pin, impact and release pendulum by  pressing the control button. 

2. 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.
