Hardness Tester

The Ultrasonic Contact Impedance (UCI) 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.
Built-in camera allows user to picture of testing object and mark tested area with corresponding hardness value.

UCI Hardness Tester T-U3 has the sealed housing with rubber protective strips, it is ideal for use in workshop, and field conditions with high humidity, dust, etc. The hardness tester has frost-resistant display, which allows user to use the device at any season and in any climatic zone of the Earth.
The device has PC software with a comfortable and intuitive interface.

The UCI hardness measuring method complies to ASTM A1038.
The ultrasonic contact impedance (UCI) probe is purposed to be used for hardness measuring in the case of the testing area minimal thickness (from 1 mm), objects of complex surface shape, and for measuring surface hardened layers hardness.
This method is very fast and easy: place the probe on the tested object surface, press the probe with the required effort to the surface and save 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 NOVOTEST T-UD3 with UCI probe leaves much smaller prints (imprints) than the majority of bench hardness tester would. That’s why a portable hardness tester with UCI probe is the best choice.

We have the CE certificate of conformity for Portable UCI Hardness Tester T-U3.
