Sauter HMM Leeb Hardness Tester Overview

The Sauter HMM Leeb Hardness Tester is a mobile Leeb hardness tester for professional metal hardness testing, using the impact rebound method to convert the measured speed reduction into Leeb hardness values. Designed for demanding applications, the HMM series combines portable operation with an external Type D impact sensor, automatic measurement direction compensation and automatic unit conversion for practical hardness assessment in the field or workshop.

This instrument is suited to hardness checks where stationary table-top devices are not practical, including large components, installed machinery, steel structures and metal parts that need to be tested on site. Its mobile format supports inspection teams working across automotive, metal processing, energy, oil and gas, and aerospace engineering environments.

Why Choose the Sauter HMM Series?

The HMM series is built around flexibility, with all measurement directions possible through 360° automatic compensation and results displayed with useful measurement context including average value, impact direction, date and time. The included hardness test block supports calibration checks, while the robust carrying case helps protect the tester during mobile use.

Built for Professional Metal Hardness Testing

For UK quality control teams, inspection engineers and production users, the Sauter HMM provides a practical Leeb hardness testing solution for metals where mobility and repeatable test handling are important. It is especially relevant for users who need portable hardness measurement across industrial sites, fabrication areas, maintenance locations and engineering inspection tasks.
