astm charpy v notch test machine

300J Charpy pendulum impact tester for impact test hammer price JB-300B

Product Description

Usage and Characteristics

The impacttesting 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.
