indenter

An indenter is a tool or device used to press into a material's surface to measure its hardness or other properties. Think of it like a small, precise stamp that applies a controlled force to see how the material responds—whether it dents easily or resists pressure. This helps scientists and engineers understand the strength, durability, and other characteristics of materials like metals, plastics, or ceramics. Indenters are essential in quality testing and research, providing valuable data about a material’s ability to withstand forces during use.
