Durometer

/djʊˈrɑmətər/ noun

Definition

A device used to measure the hardness of a material, especially rubber, plastic, or other soft materials.

Etymology

From Latin 'durus' (hard) combined with Greek '-meter' (measure), literally meaning 'hardness-measurer.' This scientific instrument term was created in the early 20th century as materials science developed.

Kelly Says

Engineers use durometers to test everything from tires to phone cases—the scale ranges from 0-100, and it's the reason some rubbers feel bouncy while others feel stiff, making it invisible but essential to almost every product you touch.
