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.
