Hardness tester

Hardness tester. Positioned in cleanroom F-2

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

The measured standard hardnesses are 2xx HV, 4xx HV and 6xx HV. The QC is performed x times a year. The QC procedure
