The 3805B is designed to fit comfortably and firmly in your hand. Its large LED display and simple three button control make the 3805B Durometer easy to use. The 3805B measures Shore A values for a wide variety of soft materials including: rubber: soft vulcanized (i.e. tire), natural nitrile; elastomeric materials (rubber and rubber-like): GR-S, GR-1, neoprene, thiokol, flexible polyacrylic esters; other softer materials including wax, felt, leather etc. (materials that would normally yield under fingernail pressure). The manual for this item comes on a USB thumb drive included in the box. Note: These units are not designed to ASTM specifications and cannot be certified as such.
