RB 3000 Rubber Rebound Resilience Tester
Essential to R&D or quality control, the RB 3000 rubber rebound resilience tester determines the resilience and shock absorption properties of rubber and elastomeric materials. Utilizing a multi-language 5” touch screen display, the RB 3000 effortlessly guides users through each testing sequence. The pendulum mechanism features a 15mm diameter hammer fin connected to an air bearing system. The bearing system is then connected to a high resolution non-contact encoder guaranteeing the highest precision in pendulum angle measurement.

Features & Applications
