Sauter HMM Leeb Hardness Tester

The Sauter HMM series provides portable Leeb hardness testing with an external Type D impact device for suitable metal components. It is intended for workshop, production and field measurements where a stationary hardness tester is impractical.

Choose the HMM package with printer or the HMM-NP version without printer. Both versions are available with an optional calibration certificate.

Optional Calibration & Certification

Add an optional calibration certificate to document your instrument’s performance before use and support your quality records. Find out below what testing is included and what your certificate provides.

Who issues the certificate?	The calibration certificate is issued by KERN & Sohn for your Sauter hardness tester.
What testing is included?	Following a functional check, the tester is checked by repeated measurements on reference blocks of known Leeb hardness. The hardness levels and scope of testing are recorded on the certificate.
What does the certificate report?	The certificate identifies the instrument, impact device, reference blocks and calibration conditions. It records the individual readings, mean, minimum and maximum values, and percentage deviation from the reference hardness.

FAQs

What measurement method does the Sauter HMM use?

It uses the Leeb impact rebound method, where the speed reduction of the impact module is measured and converted into Leeb hardness values.

Is the Sauter HMM suitable for on-site hardness testing?

Yes, its mobile design, external Type D impact sensor and carrying case make it suitable for portable industrial hardness testing.

Can the tester measure in different directions?

Yes, all measurement directions are possible thanks to automatic 360° compensation.

Which industries is this Leeb hardness tester intended for?

It is suitable for automotive, metal processing, steel construction, energy, oil and gas, and aerospace engineering applications.
