1. Function

JB-300B semi-automatic impact tester isused to determine the anti-impact capability of metal materials under dynamicload. The pendulum can raise and drop automatically. It is designed accordingto national standard GB/T3808-2002 “Pendulum Impact Test Method for Metals” andGB/T229-2007 “Metal material-Charpy notch impact test method”.

2. Features
1) Safety pin guarantees the impact action, standard protection shell to avoidany accident;

2) Easyoperation, high working efficiency;

3) Impactenergy is optional according to customers’ requirements;

4) Twocontrol types: micro control type and digital display type.
