| PTC "D" Scale Durometer 307L
These instruments feature a heat-treated, high carbon steel mainspring that is precision and centerless ground. Each spring is calibrated to meet or exceed ATSM Specification D2240-81. A special cam permits a scale deflection of 100 points when the indenteris displaced exactly 0.100 inch. The dial scale is extended over 240 circular degrees to provide reading accuracy to within +/- 0.5 divisions. A threaded mounting knob at the top of each durometer permits permanent test stand emplacement. An ancillary pointer will register the highest durometer reading against all vibrations met in normal use. Each durometer comes complete with carrying case and test block.
