JBW-300B Computerized Semi-automatic Charpy Pendulum Impact Testing Machine

1.Performance Description:

JBW-300B Computerized Semi-automatic Charpy Pendulum Impact Testing Machine is used to measure the impact

resistance of metal materials under dynamic load,so as to judge the quality of materials under dynamic load.

This machine is a computer semi-automatic control testing machine with simple operation and high working efficiency.

It is electrically controlled to swing, impact and swing. It can automatic swing and prepare for next test by using the

residual energy after breaking the sample.

It is especially suitable for laboratories that continuously do impact test and metallurgy and machinery manufacturing

industries that do a large number of impact tests.
