Combined Hardness Tester NOVOTEST T-UD2
Combined Hardness Tester NOVOTEST T-UD2 is designed for rapid non destructive hardness testing of :
- – Metals and alloys on standardized hardness scales;
- – Metals with other properties from steel (for example, non-ferrous metals, alloys, cast iron, etc.) with additional scales for calibration;
- – Use the scale of tensile strength (Rm) for determining the tensile strength of carbon steel products pearlitic by automatically converting from Brinell (HB) hardness scale.
Device implements 2 methods of testing: rebound (Leeb) and ultrasonic contact impedance (UCI). The combination of both methods allows user to test all range of metal products.
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.
