  • The NOVOTEST T-UD3 hardness tester is designed to determine the hardness of products made of metal alloys. It is the most versatile modification of the NOVOTEST hardness tester due to its configuration with two types of probes – dynamic (Leeb) and ultrasonic (contract-impedance) and combines the advantage of two measurement methods.

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 combines 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.

The main advantages of the Combined Hardness Tester NOVOTEST T-UD3:


The user can measure the hardness of completely different metal products of different shapes, structures, materials and the degree of surface preparation with same unit, just replacing probe.


Using the UCI, the operator can measure small products, we recommend parts weighing from 100 gr and a thickness from 1 mm, and when using the UCI Probe Test Stand NOVOTEST, even thinner.


Also, with the help of the ultrasonic probe, the user will be able to solve the tasks of measuring the hardness of grooves, surfaces of small radius, inaccessible places and products of complex shape.



Due to the fact that the UCI probe has a penetration depth of only a few microns, it becomes possible to work with products with high print requirements (the maximum non-destructive method is required), as well as measure the hardness of hardened layers, such as nitriding and cementation.


Using a dynamic probe (Leeb probe), the user can test the hardness of massive products with poorly prepared surfaces. The method also allows to measure products with a coarse-grained structure without a significant dispersion of measurements.


Thanks to the presence of built-in calibrations of the Leeb probe for various materials and scales, the device becomes a universal tool for measuring hardness for most common metals.


The device has a built-in camera, which allows the user to store a measurement archive of images of the tested objects with binding of hardness to a specific place on the product.

Combined Hardness Tester NOVOTEST T-UD3 can be used with special soft for operate with saved archive of measurements. Or each saved recording cab be printed throug wireless printer that can be additionaly completed with the device.

Innovation! Optionally, the device can be equipped with a Bluetooth module!

Hardness testers have never had such opportunities! Using a Bluetooth connection, your smartphone connects to the hardness tester and you have a completely new device – a new generation hardness tester! The intuitive interface, ample opportunities for documenting results, Internet access, touch screen, camera, microphone and GPS receiver of a smartphone turn your hardness tester into something completely unique and previously inaccessible.Do hardness measurements, calibrate the device, set up a convenient display of values, save the results of hardness measurements, synchronize the archive with your other devices and a PC, transfer measurement results to your colleagues – all this is available with your smartphone thanks to the special NOVOTEST app for Android.
