XJJU-50A Digital IZOD and Charpy impact testing machine into use for determining the rigid plastics, strengthen the impact toughness of nonmetallic materials such as nylon, glass fiber reinforced plastic, pottery, cast stone, plastic electric apparatus, insulating material. This machine adopts the technology of photoelectric encoder to examine angle, the whole digital measures the material absorption energy and impact intensity of the material in the course of breaking, and possess intact energy and lose detection and revision function. High precision and stability, large test range. The tester is a kind of whole digital impact testing machine. By changing the weight at the end of pendulum it can get many kind of test energy.
