Charpy Impact test machine Model JB-300B Semi-automatic pendulum impact testing machine


Main Advantages:

  the impact testing machine is used to test metallic materials to resist the impact to determine the nature of the material under dynamic load performance. It's a necessary testing machine,not only used in the metallurgy, machine manufacture etc areas, but also used for the science research.

It can Controlled by computer and electric appliance, this machine can auto-complete the following actions: rising pendulum, hanging pendulum, sending specimen, positioning, impacting, temperature conditioning and computer measurement and calculation, which also can display the results and printed out with high efficiency and high accuracy.

after impacting the specimen, the machine can rise pendulum with surplus energy automatically so as to be ready for the next test.
