This machine is mainly used to measure the impact resistance of metal materials under dynamic load, so as to judge the properties of materials under dynamic load.

This machine is a semi-automatic control testing machine with simple operation and high efficiency. It is controlled by swinging, impact and setting-off electrical apparatus. It can automatically swing the remaining energy after punching the sample to prepare for the next test. It is especially suitable for continuous impact testing laboratories and metallurgical and mechanical manufacturing industries which do a lot of impact testing. JB-300B impact tester conforms to GB/T3808-2002 "Test of pendulum impact tester". According to GB/T229-2007 "Metal Charpy pendulum impact test method", the impact test of metal materials is carried out.
