  • Specification



    JB-300B/500B series impact testing machines are used to determine the impact toughness of metal materials under dynamic load. The pendulum of the machine can be raised or released automatically. They have the features of easy operation, high efficiency, safe and reliable. The machines are especially suitable for laboratory, metallurgy industry, machinery production, steel plant and other fields.

    Key Features

    1. Pendulum rising, impact, free releasing is realized as automatically by micro control meter or remote control box.

    2. Safety pin guaranties the impact action, standard protection shell to avoid any accident.

    3. Pendulum will automatically rising and ready for next impact action after specimen breakout.

    4. With two pendulums (big and small), LCD touching screen display the energy loss, impact tenacity, rising angle, and test average value, meantime the dial scale show test result as well.

    5. Built-in micro printer to print test result.
