Type SL: For Foam Sponge Rubber,

The Model 302SL Foam & Rubber Durometer is a unique instrument that measures the hardness of soft materials such as foam rubber, sponge rubber, cellular material and gel-like materials. This instrument can perform comparative hardness tests on foam or sponge rubber without the cost of using an indention load deflection (ILD) test machine. The PTC® Model 302SL offers a cost-effective means of checking these materials with speed, portability, and accuracy. The Model 302SL is based on the force of a variable load over an area of one square centimeter. The instrument is simple to use and can be used in conjunction with the Model 470 Test Stand for faster and more precise testing. Several readings should be made and the results averaged. The sample should have an area of at least 1-1/4" square and be at least 3/4" thick. Thinner materials must be stacked (do not glue) to obtain this thickness.

The durometer can be used either with a test stand, hand-held. Please refer to the stand selection guide for the appropriate accessories. The PTC® classic style Durometer comes complete with carrying case, test block and magnetic max hand.
