Sponge Rubber Durometer
Models feature a heat-treated, high carbon steel mainspring that is calibrated to meet or exceed ASTM Specification D2240-81
Special cam permits a scale deflection of 100 points when the indenter is displaced exactly 0.100 inch
Threaded mounting knob at the top of each durometer permits permanent test stand emplacement
Resettable ancillary pointer will register the peak durometer reading against all vibrations met in normal use
Foam and sponge rubber durometer measures the hardness of soft materials such as foam rubber, sponge rubber, jells and doughs
Classifies cellular rubbers of the sponge and foam type as "x-soft", "soft", "medium" and "firm" and then divides these ranges into smaller increments
