The resulting indent is measured by either the depth of penetration or the dimensions of the resulting indentation. Hardness testing plays a vital role in materials testing, quality control, and component acceptance. Buehler provides a complete range of indenters designed for Vickers, Knoop, Rockwell, and Brinell scales.
