Measuring method according to DIN 50159 and ASTM A1038
Robust metal casing
Individual material calibrations
Extensive storage and statistical functions
Applicable for automated measurements
The alphaDUR II has proved its worth as a reliable and versatile hardness tester since many years. It can be employed from simple manual measurements to fully automated production testing.
The operation of the alphaDUR II is very easy because all information is shown on the large display. Hardness scale and material can quickly be changed by context-sensitive function keys.
Due to the UCI measuring method measurements can be done fast and accurate. The measured value is displayed directly after the test load has been applied. A test load between 0.3 (HV 0.3) and 10 kg (HV10) can be chosen depending on the application and the sample surface.
More Information for the selection of an propper probe are available in our application support documents.
