The alphaDUR mini is the small and handy variant of the alphaDUR which has been successfully used in hardness testing since many years. The technology is identical and the accessories are compatible. The operation of the alphaDUR mini is very easy because all information is shown on the large display. Hardness scale and material can quickly be changed by special keys.
Incoming goods inspection. Hardness testing of metals in production. Testing of machine parts, weld seams, coatings and hardened parts even at difficult to access locations and at any angle.
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 kg (HV 0.3) and 10 kg HV 10) can be chosen depending on the application and the sample surface.
