Impact Testing Machine JB-300

Product Description:
JB-300 type impact testing machine is used to measure the performance of metal material under dynamic load to resist impact, so as to judge the nature of material under dynamic load. This machine is in accordance with the national standard GB/T3808-2002 "pendulum impact testing machine testing" development and production of metal materials, the impact test according to GB GB/T229-2007 "metallic materials Charpy pendulum impact test method", the maximum impact energy is 300J, and comes with a 150J pendulum, the cross-section of the sample is 10 * 10mm; testing machine has a larger impact energy, so the main test for impact toughness of ferrous metal, such as steel and alloy. The pendulum impact testing machine and the potential impact of before after the remaining potential only displayed in the dial on the way, get absorbed energy of samples.
