This machine is used to measure the concave hardness of porous elastic materials. It can measure the polyurethane sponge foam samples and carry out the tests specified in the national standards, and accurately measure the indentation hardness of sponges, foams and other materials. It can also be used to measure the specified indentation hardness of the produced seat foam (such as backrest, seat cushion foam, etc.), and accurately measure the indentation hardness of each foam part of the seat.
