NOVOTEST T-U3 Digital UCI Portable Hardness Tester

The most popular portable hardness tester in the world is the Leeb hardness tester, however, there are tasks that using this method is very difficult or even impossible to solve. This is due to the physics of the method, which assumes the massiveness of the testing object, to ensure the inertness of the product when the Leeb’s impact body hits the surface with a given force. In order to solve a wider range of tasks on the rapid measurement of metal hardness, our company offers hardness testers that implement the method of ultrasonic contact impedance (UCI) in accordance with ASTM A1038. A vibrating rod (mechanical resonator) with a diamond tip acts as an indenter in these devices, when it indent into the material, the base frequency of the resonator changes, on the basis of which the hardness is calculated. This method has proven itself around the world and has been used in industry for over 50 years. – novotest web   UCI probe types 1kgf (10N) 2.2 lbf 5kgf (50N) 11lbf 10kgf (98N) 22lbf Measuring range (with standard calibration) HRC:20~70 HB:90~650 HV:230~940 User calibrations for any range (for example: HV100-1600) Measuring accuracy HRC: 2HRC HB: 10HB HV: 15HV Standards ASTM A1038 ASTM E140 ISO 18265 DIN50159 GB/T 34205 Indenter Diamond indenter (UCI) Measuring direction Any direction 360° Data storage Limited only by the memory card Communication Upload data to PC and export as a spreadsheet (USB cable and software included ) Hardness scale HRC, HB, HV, MPa Additional custom scales for calibration Materials Pre-calibrated for steel Additional custom materials for calibration Data display Load applied/contact (UCI) Single test result Max, Min, Average of tests Number of tests Deviation Var. coeff.
