Performance description
1.JBDS-300C Ultralow-temperature Automatic 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.
2.JBDS-300C is Digital Display ultralow-temperature Automatic Impact Testing Machine, which
adopts hand control box control, 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.
3.After impacting the specimen, the machine can raise pendulum with surplus energy automatically
so as to be ready for the next test.
