Ernst STE/A & STE/B: Proven Brinell Hardness Testers Used Globally Since the 1980s
The STE hardness testers have been a trusted standard in Brinell hardness testing since the 1980s — delivering precise, consistent results on small surfaces and complex shapes through Ernst’s patented shear pin system.
At the heart of the STE is an innovative shear pin system that precisely controls the force applied during indentation, ensuring reliable and repeatable measurements. Its compact design enables hardness testing in all positions on parts of any shape and size — even in tight or challenging locations.
All Brinell hardnesses from 100 to 700 HB are covered with minimal investment. Each unit ships with original Ernst patented shear pins and corresponding reading tables for a complete, stand-alone testing solution.
