Ultrasonic Hardness Tester is a portable durometer for hardness testing of the coating and plating. It can measure the hardness of chrome, copper plating, carburized layer and nitriding layer effectively.

The UCI hardness measuring method complies the standard ASTM A1038-2005 and DIN standard DIN50159-1-2008

The manual probe is used for measuring the hardness value of small items, objects with a thin wall, complex form, and to measure the hardness of surface hardened layers, welds and the HAZ. 

The ultrasonic contact impedance (UCI) probe is to be used for hardness measurement in the case of sample piece with minimal thickness (from 1 mm). Also objects of complex surface shape, and for measuring surface hardening layer hardness.

This method is very fast and easy: place the probe on the tested object surface and apply the required test force to the surface. The main unit makes the measurement, saves the hardness value, shown on the display of the device. Small size diamond indenter allows measuring hardness value of all items, which are thicker than 1 mm.

The UCI method of hardness testing is the least destructive because the hardness tester with UCI probe leaves a smaller imprint than the majority of bench hardness tester would (similar to Vickers indentation size).
