Sponge Surface Hardness Tester

The sponge surface hardness tester measures the depth of penetration or rebound force by pressing a needle into the sponge surface under constant pressure, reflecting the softness or hardness of the material. It is used to test the support and comfort of soft foams, such as those in sofas, mattresses, and packaging materials, and to guide adjustments in production processes.
Selection
When selecting, consider the sponge thickness and ensure the indenter size matches the test standards. Use a spherical indenter for conventional products, while high-resilience materials require a conical indenter. Verify that the measurement range covers the hardness range of the material being tested, and prioritize models with a flat support base to avoid deformation during testing. Regularly validate the instrument's condition using standard hardness blocks.
