JBS-300B 150J 300J Digital Display Charpy Impact Strength Testing Machine
1. Application
JBS series digital display Pendulum impact tester 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.
