The alphaDUR III is a portable UCI (Ultrasonic Contact Impedance) hardness tester designed for fast, accurate, and non-destructive hardness testing of metallic materials. It is ideal for incoming inspection, production quality control, weld testing, coatings, and hardened components, even in difficult-to-access locations. Featuring a robust metal housing, intuitive operation, multiple hardness scales, and extensive data storage and statistical functions, the alphaDUR III delivers reliable hardness measurements in both workshop and field environments.
The alphaDUR III has proved it‘s 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 III 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.
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.
