The measuring head contains the intender which is generally a diamond pyramid with 136° plane angle.
It is checked for quality under DIN EN ISO 14577-2 standards.
Indenters with a diamond pyramid according to Berkovich or with hard metal spheres are available as well.
The controlled touchdown of the measuring head leads to a very small machine compliance.
The measurement of the indentation depth is carried out with a resolution in the picometer range.
The micro hardness determination is computer controlled, free of any subjective influence, and thus independent of the operator.
