Impact strength meter

Impact strength meter usually adopts pendulum or drop hammer principle. The pendulum impact strength meter is to raise the pendulum to a certain height, then release the pendulum to hit the sample, measure the energy loss of the pendulum before and after the impact, and calculate the impact strength of the material. The drop hammer impact strength meter is to let a certain mass of drop hammer fall freely from a certain height, hit the sample, measure the energy loss of the drop hammer before and after the impact, and calculate the impact strength of the material.
