The alphaDUR mini II is the fourth generation of the alphaDUR series, which has been successful for many years.
The operation of the alphaDUR II mini is very easy because all information is shown on the large LCD display. Hardness scale and material can quickly be changed by special keys. 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 and 10 kg can be chosen depending on the application and the sample surface.
