| PTC Sponge Rubber Durometer 302SL
Foam and Sponge Rubber Durometer measures the hardness of soft materials such as foam rubber, sponge rubber, jells and doughs. It classifies cellular rubbers of the sponge and foam type as "x-soft", "soft", "medium" and "firm", and then further divides these ranges into smaller increments so that much closer and accurate tolerances can be established. This instrument can perform comparative hardness tests without the cost of using an indentation load deflection (ILD) test machine. Model 302SL offers a cost-effective means of checking foam or sponge rubber with speed, portability and accuracy.
Values of the 302SL scale are based on the force of a variable load over an area of one Square centimeter. When making hand-held tests, the gauge is simply placed on the material to be checked. No external force is needed, the weight of the instrument itself is sufficient to bring the base of the gauge flush with the material's surface. When using with a test stand, the material and the stage are lifted up to the durometer until the load cell of the stand separates. The resettable ancillary hand records the peak reading.
Accurate readings require that the sample be at least 3/4 of an inch thick. Thinner materials should be stacked to equal this thickness. Several readings should be made and the results averaged.
Each instrument comes complete with carrying case and test block. |
