Portable Hardness Testers

Our portable Rockwell hardness testers are the result of more than 60 years' experience. They have proven themselves in many branches of industry for decades.

The heart of every tester is the reliable spring sleeve unit for load application. The hardness value is indicated on an analogue dial gauge.
