1.Application:
JBW-B Computer Control Semi-automatic Charpy Impact Testing Machine are mainly used to determine the anti-impact capability of metal materials under dynamic load.
Carry out the functions of zero clearing and automatic return, capturing the value of lost impact energy and pendulum cycle by means of setting up with computer program,and the results can be monitored, stored and printed out. Control box or computer program control is alternative operating method. JBW-B Computer Control Semi-automatic Charpy Impact Testing Machine are adopted by many institutes and high-tech enterprises.
