LFY-708C Elastomer Load-Dependent Impact Fatigue and Hardness Testing Instrument

Primary uses

Suitable for determining the reduction in thickness and decrease in hardness of porous elastic materials, soft foam, and sponge after impact under a specified load. It can also measure the indentation hardness of porous elastic materials.
