Sponge Resilience Tester
Model：JH-HMV-01
Sponge resilience testeris aprofessional testing sponge, foam, rubber and other soft materials and thedesign of a cost-effective instrument.The ball is mainly free falling on a sample ofsoft foam or other elastic materials. It is an instrument used to measure therebound height, mainly used to measure the rebound energy (rebound coefficient)in the test item of polyurethane elastic material.

Principle：
Sponge, foam, rubber and other materials should be storedfor at least 72 hours after molding before testing. Before the test, the sampleshould be in the temperature of 23 + 2 ℃, relative humidity 45% - 50%of the state of environment regulation at least 16 hours, and then in theenvironment for testing.
