Hardness tester

The purpose is to measure hardness of samples or films. This is done by pressing an indenter (a small pyramid-shaped diamond tip) into sample using a known indentation force. This leaves an indent in the sample. The hardness of the sample can then be derived from the dimensions of the indentation (the softer the material the larger the indentation).

The user manual, technical information and contact information can be found in LabManager:

Quality Control (QC) for the hardness tester

There is no scheduled calibration of this machine. We do however have three calibration samples which can be used to verify proper operation of the machine. The calibration samples are also good for practicing the measurement procedure. The calibration samples are available in the following three hardnesses: 2xx HV, 4xx HV and 6xx HV.
