Durometers are precision instruments used to measure the hardness of materials, particularly rubber, plastics, and other elastomers. These devices are essential in quality control and material testing across industries like automotive, manufacturing, and construction. They provide quick, non-destructive hardness readings using standardized scales (e.g., Shore A/D). Industrial durometers feature rugged designs for shop-floor use, with options including analog dials or digital displays for accuracy. Common applications include tire production, conveyor belt maintenance, and polymer product verification.
