The most common instrument used for measuring hardness is Shore Durometer. It measures the depth of penetration of an indenter on a scale from zero to a tenth of an inch (0.1 in.).

(See table, Shore hardness testing) Each scale ranges from 100 (a lack of indentation) to 0 (a maximum indentation that varies by scale). Most scales are based on 0.1 in. maximum indentation.

The hardness testing machines and instruments from ZwickRoell work based on the company’s years of experience in offering an extensive range of equipment used across the globe and communicating with ...

Instron Corp. is marketing its new Shore S1 Durometer, which features a modular cartridge system. The system allows operators to test in any of the standard Shore scales-A, B, D, C, DO, O, OO and M.

Here is more information for understanding how these couplings can be used beyond transmitting rotary motion and compensating for misalignment between shafts. It covers sizing, selection and how ...
