1. Features of JB-300 manual impact testing machine

The JB-300 manual impact tester is mainly used to measure the resistance of metal materials to impact under dynamic load, so as to judge the quality of the material under dynamic load. The manual control mode is adopted , and the pendulum, impact and braking are operated manually. This machine is suitable for ferrous metals with large impact toughness, such as the impact performance test of steel and its alloy materials. It can be used by the material laboratories of various scientific research units, universities, metallurgy and machinery manufacturing industries to conduct metal materials Impact test.
