The cantilever beam impact testing machine is used to measure the impact toughness of non-metallic materials such as plastics, reinforced nylon, fiberglass, ceramics, cast stones, plastic appliances, insulation materials, etc. The pendulum impact testing machine is a commonly used equipment for quality inspection in scientific research institutions, colleges and universities, and non-metallic material manufacturers. It is an instrument with simple structure, convenient operation, and high testing accuracy. The digital impact testing machine adopts high-precision encoder technology, which has the characteristics of high accuracy, good stability, and large measurement range. The digital measurement displays the impact strength and average value, and the energy loss is automatically corrected, Printing test reports and other functions.
