All FISCHER instruments employ Instrumented Indentation Test method – often called nanoindentation – for determining the Martens Hardness (HM). In contrast to other hardness tests, this method not only determines the plastic behaviour of the material, but additional material parameters can also be read from the measurement plot, such as the Elastic Modulus of Indentation (EIT), the Indentation Hardness (HIT) and the Indentation Creep (CIT), as well as the plastic and elastic deformation energies
