Hardness Testers

Hardness is the resistance of a material against the intrusion of another (harder) body.

We manufacture the various diamond indenters according to applicable procedures and standards.

The geometry of the diamond indenter to measure hardness is determined by the respective standard:

Hardness measurement according to:

ROCKWELL:     cone 120° with radius r = 0.200m

VICKERS:         pyramid 148°7` edge angle / 136° surface angle

KNOOP:            rhomboid with 130° respectively 172°30` edge angle

BERKOVIC:      3-sided pyramid (tetrahedron)

The diamonds are set using a high strength, non-rebounding bond for the normal hardness testing machines.
  • Standard types for laboratory equipment
  • Special mounts for automatic machines and special devices
