Type Impact Testing Machine
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 dynamiv load. This machine makes
use of difference between gravitational energy before impacting to display
value on dial and get the sample absorbing energy.

What the host of
tis machine adopts casting steel material can make equipment run steadily at
the whole process of the test and get more accurate result. It has the
advantages of manual operation, without power, low cost and is applied to
department or schools whose testing volume is smaller.
