Ultrasonic Contact Impedance (UCI) Hardness Tester
An impressive and enduring diamond
The UCI method (Ultrasonic Contact Impedance) enables a quick and easy evaluation of hardness indentations according to Vickers without using a microscope. A Vickers diamond is attached to the lower end of a metal rod which is excited to oscillations by piezoelectric elements. When the diamond penetrates the material to be tested, there is a change in the resonant frequency of the metal rod. This change increases as the indentation surface becomes larger. Because of the size of the indentation surface on its part is a measure for the hardness, there is a direct relationship between the frequency change and the material hardness. The evaluation of the measurement just takes a few milliseconds !

In our range of portable hardness testers, we offer a portable, Ultrasonic Contact Impedance (UCI) technique based hardness tester, Model alphaDUR, standardized according to ASTM A 1038 from our principal company M/s BAQ GmbH, Germany.
This UCI hardness tester is offered with narrow handheld probes having Vickers diamond at the tip and in different testloads to suit a wide range of applications. It is most ideal to determine material properties within narrow tolerances.
Typical applications include the following:
- Testing of fine grained materials of different masses, shapes and in (Induction/Carburized) hardened mechanical parts.
- Measurements on finished assemblies, parts having smooth and polished surfaces.
- Hardness testing on layers e.g. copper, chromium etc on steel cylinders.
- Testing on finished precision parts, gears, bearing raceways etc.
- In container and pipeline construction, welds & HAZ are also evaluated.
- Measurement in grooves, gear tooth flanks and roots.
- Ion nitrided stamping dies and molds, forms and presses, thin walled parts etc.
- udging the mechanical characteristics and wear resistance of steels as well as about the ageing process of metal parts
The instrument provides for a high measuring accuracy, conversion and display of hardness measurement in different scales, datalogging and statistical functions and is offered with all required testing accessories and peripherals.
