Computer-controlled pendulum impact tester HST JB-300B

for Charpy testing

JB Pendulum Impact Testing Machineare used to is used to test anti-impact performance of metal material under dynamic load to judge the quality of material under dynamic load. This machine is semiautomatic control testing machine, easy to operate, high effective. Raising pendulum, impact and pendulum dropping are all controlled by electrical equipment.
