🔩 How the Leeb Hardness Tester Works — Explained Simply! The Leeb hardness testing method is based on measuring the rebound velocity of a small impact body after it strikes the test surface. Here’s how it works in the NOVOTEST T-D2 (Lab) and similar devices: 1️⃣ The impact body (with a hard metal tip) is launched at high speed onto the test material using a spring mechanism. 2️⃣ Upon hitting the surface, the body rebounds. The device measures both the impact velocity and the rebound velocity us
