NOVOTEST T-UD3 Combined Hardness Tester
Combined Hardness Tester NOVOTEST T-UD3 combines two methods of measuring hardness by an indirect method: Ultrasonic Contact Impedance (ASTM A1038) and Leeb (ASTM A956). This makes the device the most versatile portable device in the world.
The ability to connect both probes combine the advantages of both methods and providing users the opportunity to use the one that is most suitable for solving a specific task. The Combined Hardness Tester NOVOTEST T-UD3 allows user to measure the hardness of any metals, parts of any shape and thickness, measure the hardness of the surface hardened layers and evaluate the tensile strength.

NOVOTEST T-U3 UCI Hardness Tester
The UCI NOVOTEST T-U3 Hardness Tester has a sealed housing with protective rubber strips and is ideal for use in the workshop and in open spaces where humidity is high. The hardness tester has a frost resistant construction, which allows the user to use the device in any season and in any climate zone on Earth.
The Ultrasonic Contact Probe (UCI) is used to measure the hardness value of small objects, thin-walled objects, complex shapes and to measure the hardness of hardened surface layers.
The built-in camera allows the user to photograph the test object and mark the tested area with the appropriate hardness value.
The imprint after measuring the hardness by the UCI method is several microns, and is practically not detected by the naked eye, in comparison with the Leeb method, the imprint of which is about 500 microns in diameter, depending on the hardness. It also makes it possible to measure the hardness of hardened layers of materials (nitriding, cementation, etc.)

NOVOTEST T-D3 Leeb Hardness Tester
The Leeb method of hardness testing of metals is the most popular because of its ease of use. The user does not need to have special skills and or knowledge in the field of hardness measurement, to perform the measurement, it is necessary to load the impact body of the probe of the device, install the probe on the tested surface, press the probe release button and the hardness value will be displayed on the device screen.
This method is recommended for large products, weighing 5 kg and more and 10 mm thick and more, but, subject to certain product mounting requirements, it is also possible to measure small parts.
Scales and materials – the machine comes with pre-calibrations for various scales and materials, making the machine universal.
- Scales: HRC, HRB, HB, HV, HL, MPa.
- Materiales: steel, alloy steel, cast iron, stainless steel, aluminium, bronze, brass, copper.
Low surface quality and material structure requirements
The Leeb NOVOTEST T-D3 hardness tester can be used for products with a poorly prepared surface (roughness of 3.2 Ra and more) as well as for materials with a coarse-grained structure, such as cast iron and others.

NOVOTEST T-UD2 Combined Hardness Tester
Combined Hardness Tester NOVOTEST T-UD2 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 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.
