The alphaDUR mini II is the fourth generation of the alphaDUR series, which has been successful for many years.
Operating the alphaDUR mini II is very convenient and clear, as all information is shown on the large LCD display. The hardness scale and material calibration can be changed quickly using special buttons. With the UCI (Ultrasonic Contact Impedance) method, measurements are quick, precise and independent of direction. After applying the test load by hand or in the stand, the hardness value can be read off immediately. Depending on the application and surface, a hand probe with a test load of between 3 and 98 N can be selected.
