The Microcomputer Sponge Resilience Tester is a high-performance instrument designed for testing sponges, foams, rubber, and other soft materials. By freely dropping a steel ball onto the sample, the tester measures rebound height and calculates the rebound coefficient. It is widely applied in polyurethane foam elasticity testing and other rebound performance assessments. Functions & Applications This tester is suitable for evaluating the resilience and elasticity of sponges, foams, and rubber materials. It ensures accurate measurement of rebound rate, making it essential for quality inspection, R&D, and production monitoring in furniture, mattress, automotive, and cushioning material industries.
