Specifications

Rubber Hardness Tester

The IRHD Hardness Tester is a table model equipment suitable for reference testing of hardness of rubber or similar polymers in the laboratory. It consists of a plunger rod carrying a hardened hemispherical tip of the specified diameter at its lower end. The rod is located within a cylindrical guide and is constrained to move inside it. The base of the guide acts as the pressure foot surrounding the point of indentation. Under normal condition the pressure foot extends below the indenting tip, thus preventing it from getting damaged. An indenting load is positioned over the plunger rod without directly acting on it.
