Product Description

D+15 Impact Probe for Leeb Hardness Testing

The D+15 Impact Device is a specialized probe designed for Leeb hardness testing in confined spaces. With dimensions of F20 × 162mm and weighing only 80g, this compact probe enables precise surface hardness measurements in grooves, pits, and other hard-to-reach areas.

Available Impact Device Types

DC: For testing holes or hollow cylindrical surfaces
D+15: For testing grooves or reentrant surfaces
C: For testing small, light, thin parts and surface hardened layers
G: For testing large, thick, heavy and rough surface steel
E: For testing super high hardness materials
DL: For testing slender narrow grooves or holes
