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 samples should have a reasonably low roughness. Otherwise it can be quite difficult to determine the roughness reliably.

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. Calibration samples are available in the following three hardnesses: 277 HV, 464 HV and 704 HV. They have been calibrated using a test force of 1 kgf and an indentation time of 10 sec. |
