VICKERS HARDNESS TESTERS

Vickers is a hardness test for all solid materials. It is calculated by measuring the diagonal lengths of an indent in the sample material left by a diamond pyramid indenter with a given load. The diagonals of the indent are measured optically to determine the hardness, using a table or formula.

KNOOP HARDNESS TESTERS

Knoop is an alternative to Vickers in the micro hardness testing range. It is mainly used for brittle materials and to facilitate the hardness testing of thin layers. The indenter is an asymmetrical pyramidal diamond, and the indent is measured by optically measuring the long diagonal.

BRINELL HARDNESS TESTERS

Brinell is used for hardness testing larger samples with a coarse or inhomogeneous grain structure. The indentation leaves a relatively large impression, using a tungsten carbide ball. The size of the indent is read optically.
