LECO LV-100-AT automatic hardness tester



Questions regarding wear resistance and machinability? Finding the Vickers hardness will help you choose and inspect your material.


A large number of indents can be applied on the entire sample to get a complete hardness map rather than a local measurement value at one location or on a specific line.

  • Indentation force ranging from 0.3 to 30 kgf.
  • Number of indents ranging from 1 to more than 1000 indents per sample.


  • Local hardness measurement of raw metals.
  • Hardness mapping of welds.
  • Hardness mapping of components to evaluate treatments/coatings/wear resistance.

Working principle:

A hardness test is performed by pressing a hard object (indenter) into the test material. The Vickers hardness value is achieved by measuring the area of the mark left by a pyramidal shaped, diamond indenter in accordance with standard ASTM E92 and ASTM E384.
