Durometer Tester


A durometer tester is used to measure the hardness of rubber or plastics. It works by applying a known load on an indenter and determining the amount of penetration as indicated on a dial gage. Two ranges are available including Durometer A and D. The A range instrument is better suited to harder materials like polymethyl-methacrylate or styrene plastics, while the D range instrument is commonly used for products such as butyl or nitrile rubber.
