Usage and characteristics
JB-300 type impact testing machine is used to test anti-impact performance of metal material under dynamic load to judge the nature of material under dynamic load. This machine makes use of difference between gravitational energy before impacting and spare energy after impacting to display value on dial and get the sample absorbing energy.
This machine has the advantages of manual operation, without power, low cost and is applied to departments or schools whose testing volume is smaller.
