Hardness testing device Struers DuraScan 20

Hardness Tester DuraScan 20 – Struers

Functionality

The DuraScan 20 by Struers is a semiautomatic hardness testing device with a Vickers intender, various object lenses as well as a motor-driven z-axis and object lens revolver. To measure the hardness, the machine inserts the pyramidal intender in the test sample and measures the diagonal length of the diamond-shaped indentation. Depending on the diagonal length as well as the testing force, the machine is able to determine the hardness of the tested sample.

Field of application

The big variability of the DuraScan 20 allows measurements with testing forces between 0,1 N and 100 N. Because of that, the hardness testing device is able to determine the micro hardness of single metallographic constituents on the one side as well as the macro hardness on the other side. Also the testing of curved part shapes is enabled by the special software of Struers.
