Manual and Fully-Automatic Pendulum Rebound Resilience Tester. These rebound testers will determine the dynamic behavior of various materials and supply the differentiation of these materials’ qualities. It will also identify material changes after aging and fatigue. The Pendulum Rebound Tester is out there with an adjustable heater for sample temperatures up to 100 ℃. It can simulate the effect of heat on the elasticity of samples with different formulations.
