Description

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.


Feature

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.
