Portable Hardness Testing Inside Bores and Cylindrical Components
The N6 is a portable internal diameter hardness tester designed for fast and reliable hardness testing inside bores, tubes, rings and other cylindrical components. Based on the proven Rockwell HR62.5 principle, it delivers accurate HRC hardness measurements without cutting, sectioning or transporting the workpiece.
Unlike conventional hardness testing methods, the N6 allows direct hardness verification inside finished components, reducing inspection time and eliminating destructive sample preparation. This makes it an ideal solution for production, maintenance and quality control.
Designed for internal diameters from 36 mm to 110 mm and measurement depths up to 900 mm, the N6 enables hardness testing in locations that are inaccessible to conventional bench-top hardness testers.
Its portable design brings laboratory-quality hardness testing directly to the workpiece, helping manufacturers improve productivity while maintaining reliable and repeatable quality control.
