1. Function
JB-300B semi-automatic impact tester is used to determine the anti-impact capability of metal materials under dynamic load. The pendulum can raise and drop automatically. It is designed according to national standard GB/T3808-2002 Pendulum Impact Test Method for Metals and GB/T229-2007 Metal material-Charpy notch impact test method.
2. Features
1) Safety pin guarantees the impact action, standard protection shell to avoid any accident;
2) Easy operation, high working efficiency;
3) Impact energy is optional according to customers’ requirements;
4) Two control types: micro control type and digital display type.
