JB-300 Manual Charpy Impact Testing Machine

Impact Testing Machine

I.Model and name
JB-300 Manual Charpy Impact Testing Machine

II.Equipment application
This equipment is used to measure the resistance of metal materials to impact under dynamic load in order to judge the properties of the material under dynamic load. Using the difference between the potential energy before the impact of the pendulum and the remaining potential energy after the impact is displayed on the dial, to obtain the absorption work of the sample. The maximum impact energy is 300J, and the cross section of the sample used is (10×10) mm.
The operation is manual type, easy to operate, high working efficiency.

III.Applicable standards (please consult us about other applicable standards)
