JB-300B Semi Automatic Metal Impact Tester
The JB-300B Semi Automatic Metal Impact Tester is designed for precise measurement of metal material impact toughness according to GB/T3808-2007 and GB/T229-1994 national standards. The device calculates absorbed energy by measuring the potential difference before and after pendulum impact.
- Measures impact absorption through pendulum potential difference
- Dial pointer display for clear energy measurement
- Semi-automatic operation with electric lift mechanism
- Automatic pendulum return after impact
- Efficient operation for continuous impact testing
- High precision measurement of metal toughness values
This impact tester is widely used in mechanical, metallurgical, aerospace industries, universities, and research institutions for evaluating metal material impact resistance under dynamic loads.
Primarily designed for testing impact toughness of ferrous metals, including castings, steel, and their alloys, measuring absorbed impact energy and material ductility.
