Brief Introduction: A impact testing machine is used to determine the energy absorbed in fracturing a test piece at high velocity. JB-300B is a dial display impact testing machine, which 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 machine can be operated semi-automatically. The pendulum of the machine can be raised or released automatically. With 300J and 150J pendulums separately, this machine can examine the impact energies at high precise.

Standards:  In accordance with ISO 148 or ASTM E23, GB/T229-1994, GB/T3808-2002

Applications:  Be applicable for continuing impact testing in different kinds of laboratories and other metallurgy industrial manufactories. It is a ideal equipment for quality control center, engineering areas,  college and research institute,  as well as other areas concerning material impact testing.
