Features: 1, each durometer type is made to a specific scale (i. E.A, c, d) and is capable of producing a value between 0and 100. Shore a is designed to measure the penetration hardness of rubber, elastomers and other rubber like substances such as neoprene, silicone, and vinyl. It can also be used for soft plastics, felt, leather and similar materials. Shore d is designed for plastics, formica, epoxies and plexiglass. 2, it meets standards: din 53505, iso 868, iso 7619, astmd 2240, jisk7215. 3, used the exclusive micro-computer lsi-circuit and crystal time base to offer high accuracy measurement. 4, digital display gives exact reading with no guessing and errors. 5, can communicate with pc for reading, printing and analyzing by the optional software and cable for rs232c interface. 6, automatic power off to conserve power. 7, use operation stand of optional parts can get good accuracy and repetitiveness due to constant measurement force to eliminate the errors caused by artificially applied different force. Dimensions: 162x65x38mm
