UCI hardness tester NOVOTEST T-U2 is designed for rapid non-destructive hardness testing of:
- metals and alloys on standardized international scales of hardness: Rockwell (HRC), Brinell (HB), Vickers (HV);
- metals with distinctions in properties of steel (e.g., non-ferrous metals, alloys of iron and others.) and using five additional scales for calibration;
- using a scale of tensile strength (Rm) to determine the tensile strength of carbon steel pearlitic products by automatic recalculation from Brinell (HB) hardness scale
Ultrasonic hardness tester T-U2 implements the ultrasonic contact impedance method (UCI).
UCI method for the hardness testing
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-UD2 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.
The device has the main advantages of ultrasonic hardness tester and it is very usability and reliable.

Restrictions about the using of the UCI hardness tester T-U2
Limited using of hardness tester for hardness testing of products with coarse-grained structure (eg, cast iron) or product which are weighing less than 10 grams, or thinner than 1 mm.
- Additional UCI probes. Also, after the purchase if will be needed, user can order the additional Leeb probe (D, DC, DL, C, D+15, E, G), with activation code and will get combined hardness tester with two probes (UCI+Leeb).
- Hardness test blocks
- Portable grinding machine
- Case for hardness tester
Features and applications of UCI U1 probe type:
|UCI U1 (98 N)||98 N(10 kgf)||The main type of probe for solving most problems of hardness measurement. 10 kg load is to be applied for measurement (set automatically by the probe). Low requirements for surface cleanliness.||– Heat-treated and cemented details.- Measuring in grooves, on teeth, on radius surfaces.- Measurement on the blades, on the internal surface of the pipes, openings.|
|UCI U1 (50 N)||50 N(5 kgf)||The main probe type for the most tasks of hardness measurement. 5 kg. load is to be applied for measurement (automatically controled by the probe). Average surface cleannes requirements.||– Heat-treated and cemented parts, for example, shafts, turbines, gears, teeth, welds, heat affected zones.- Measuring in grooves, on teeth, in grooves, on radius surfaces.- Measurement on the blades, on the internal surface of the pipes, openings.|
|UCI U1 (10 N)||10 N(1 kgf)||The reduced load probe is designed to measure the hardness of material with increased requirements to the print size (polished surfaces), to measure the hardness of surface hardened layers. 1 kg. load is to be applied for measurement (automatically controled by the probe).|
More sensible to the surface cleanliness, in comparison with U1 (50 N).
|– Nitrided and cemented surface layers of molds, stamps, stamps, thin-walled parts.- Bearings, lateral surfaces of saws teeth.- Measurement of hardness of hardening coatings.– Measurement on the blades, on the inner surface of the pipes, inside the holes.|
