The UCI ultrasonic tester 3000 can be used for quickly checking the hardness of components even after installation. The device offers a wide measurement range, easy handling, robust design and a temperature resistance up to -20 ° C. In addition to the hardness in Rockwell, Brinell and Vickers, the UCI hardness tester can test the tensile strength of steels up to 1740 MPa. The UCI hardness tester comes standard with a manual probe with a test force of 50N, with this probe can be measured independent of direction from all directions with no correction factor.


Another advantage of the hardness tester is its NDT property. There is a Vickers diamond, which is excited in the ultrasonic frequency range at the probe tip. Touching the diamond to the specimen surface dampens the vibrations. The resulting frequency shift is directly related to the surface hardness of the test piece. Due to the low test loads, the penetration depth of the diamond is very low, which is why only an almost invisible impression remains.

The UCI hardness tester is therefore used for the control of small thin-walled components, for surface hardened specimens or nitrided components. The hardness tester has also been effective in the measurement of welds and control of components with complex geometry.
