Sponge Hardness Measurement Device

A sponge hardness tester applies a fixed pressure to the sponge through an indenter, measures the indentation depth, and converts it into a hardness value. It is used to test the softness or hardness of materials such as sponges and foam, helping to determine whether the materials meet usage requirements in quality inspection and production control.
Selection
Select the indenter size based on the thickness of the sponge being tested, match the range according to the material's softness and hardness, use standard models for routine testing, and customize the indenter for special shapes. Consider the usage environment to choose between mechanical or digital display types, and verify the accuracy requirements specified by national testing standards.
