JBS-300B 300J/150J Touch Screen

Digital Pendulum Charpy Impact Strength Testing Machine

1.Application


JBS-300B  Digital  Display Metal Impact Testing Machine  is mainly used to determine the anti-impact capability of ferrous metal materials with high toughness, especially for steel and iron and their alloy, under dynamic load.
This series tester is operated semi-automatically, the pendulum of the machine can be raised or released automatically. Be applicable for continuing testing in different kinds of laboratories and other metallurgy industrial manufactories


2. Standards:
