JBW-300BCZThe microcomputer controlled ultra-low temperature fully automatic impact testing machine is used to test the impact resistance performance of metal materials under dynamic loads. It is an essential testing instrument for metallurgical machinery manufacturing and other units, as well as an indispensable testing instrument for research institutions to conduct new material research.

1 The impact testing machine uses liquid nitrogen refrigeration, with a minimum temperature of up to-196℃It is particularly suitable for measuring the impact resistance of metal materials at extremely low temperatures and is an important testing method for metallurgical, mechanical manufacturing, scientific research and testing units to test materials and research and develop new materials.

2 The mainframe of the testing machine is a split structure, with a cantilever hanging pendulum and a pendulum bodyUType.

3 The impact knife is fixed with screws for easy replacement.

4 Sample simply supported beam, sample end face positioning.

5 The host is equipped with security protection pins and a safety net.
