Indentation Hardness Tester For Testing Lab

Indentation Hardness Tester - For Testing Lab The feel of softness of any flexible foam is quantitatively defined by its indentation hardness. Indentation hardness is determined by pressing a circular indentor at a specified speed against a block of foam and finding the force needed to compress the block to a specified percentage of its initial thickness.   The Indentation Hardness Tester for polyurethane foam seats consists of a circular steel indentor that can be pressed against the test specimen kept on a flat horizontal surface at a specified speed with arrangement to measure the load being applied by the indentor on the test specimen, arrangement to measure the thickness of the test specimen at the start of the test under a specified load, and arrangement to stop the movement of the indentor automatically after the desired deflection.
