Model 501aR ASTM Type aR Analog Durometer (US patent 436,874 )
Type A: For Soft Rubber, Elastomers, Waxes, Printing RollersNEW ASTM "R" DESIGNATION ! The ultimate durometer for accurate hardness measurements of rubber, elastomers, and other rubber like substances such as neoprene, silicone, vinyl, nitrile, and butyl. PTC's Model 501AR has a rubber grip and a 18mm diameter presser foot conforming to the latest ASTM D2240 standards. Type R is a designation, rather than a true “type”. The R designation specifies a presser foot diameter of 18 ± 0.5 mm (0.71 ± 0.02 in) in diameter, while the spring forces and indenter configurations remain unchanged; The R designation is available on any e2000 Millennium Style Durometer, Digital or Analog. See table below.The R designation, when applicable, is expressed as Type xR, where x is the D2240 type, e.g., aR; dR; eR; etc. ASTM recommends these durometer types be used in an operating stand for maximum performance.
