Specification of Combined Hardness Tester NOVOTEST T UD2
NOVOTEST T-UD2 Combined Hardness Tester is designed for rapid non-destructive hardness testing of:
metals and alloys on standardized hardness scales;
metals with different 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 pearl tensile strength of carbon steel products by automatically converting from Brinell (HB) hardness scale.
Device implements 2 methods of testing: rebound (Leeb) and ultrasonic contact impedance (UCI). The combination of methods allows the 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 cases of minimal thickness (from 1 mm), objects of complex surface shapes, and for measuring 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 save the surface and hardness value, shown on the display of the device. Small size diamond indenter allows the measuring hardness of all items, which are thicker than 1 mm. The UCI method of destructive hardness testing because the hardness tester NOVOTEST T-UD2 with UCI probes leaves much of the smaller prints (imprints) of the would-be bench hardness tester. That's why a portable hardness tester with UCI probes is the best choice.
Leeb method for the hardness testing
The Leeb hardness measuring method complies to ASTM A956.
The Leeb probe (D type) is used for hardness measuring more than 5 kg and more than 10 mm and made of steels non-ferrous metals, cast irons, coarse grained materials, e.t.c. Also, the Leeb method perfectly complements UCI hardness measuring methods when the UCI method is not applied.
This method is very fast and easy: place the probe on the tested object vertically to the object surface, push the probe to charge the spring, press the button on the top to make measurement and save the hardness value, shown on the display . For the Leeb measuring method, NOVOTEST-UD2 automatically calculates hardness for a wide range of materials, like steel, stainless steel, cast iron, bronze, aluminum.
The combined hardness tester is the most universal, needs no recalibration, and is fully operational "out of the box".
