AMH55 Series Automated Hardness Testing Systems



Unique touch-screen interface for full control of the system, measurements and documenting


Indent hardness

Accurately measure impressions of various surface conditions, including scratched, lightly etched, or unevenly illuminated surfaces


Optional advanced analysis module enables color representation of hardness variances


Maximize your productivity and easily measure impressions on various surface conditions for a wide number of applications with LECO’s new AMH55 Automated Micro/Macro Indentation hardness testing system.

The AMH55 introduces LECO’s innovative Cornerstone® brand software to our hardness testing platforms, for increased usability, simplified reporting, and streamlined analysis times. Supporting accurate and efficient microindentation and Macro/Vickers hardness testing in fully automatic, semi-automatic, and lite configurations, the AMH55 is a valuable resource for users needing precise and productive hardness testing while tailoring the data and results to their needs.

Operator influence is greatly reduced or eliminated for both indent placement and measurement, improving accuracy, precision, and sample throughput.

The AMH55 is Ideal for many demanding applications such as  Case Depth Analysis; Coating Hardness; Surface Analysis; Powdered Metals; Weld Profiles ; Fasteners ; Decarburization and many others.

The AMH55 supports all standard loads for microindentation and Macro/Vickers hardness testing. The AMH55 conforms to ASTM E-384 for micro/macro hardness testing.
