Combined Hardness Tester NOVOTEST T-UD3
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.

UCI Hardness Tester NOVOTEST T-U3
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.

Leeb Hardness Tester NOVOTEST T-D3
The most popular method in the world for testing the hardness of metals using a portable hardness tester is the Leeb method (ASTM A956). The so-called dynamic method for determining hardness is widespread due to its ease of use. The user does not need to have special skills and or knowledge in the field of hardness measurement, to carry out the measurement, it is necessary to charge up the impact body of the device’s probe, install the probe on the tested surface, press the release button of the probe and the hardness value will be displayed on the device screen.
This method is recommended for large products, weighing from 5 kg and a thickness of 10 mm and more, however, observing certain requirements for fixing the product, it is possible to measure also small parts.

Leeb Hardness Tester NOVOTEST T-D2
The Leeb Hardness Tester NOVOTEST T-D2 correspond to to ASTM A956 is the most popular metal hardness testing method in the world, because of very easy to use and does not require special skills from the operator. The probe is mounted on the sample, and by pressing the release button, measurement is performed, and the hardness value is displayed on the device’s screen. The method works well with low alloy steels, stainless steels, as well as non-ferrous metals.
It is usually used for bulk products, without thorough surface preparation and is less sensitive to inhomogeneous or coarse-grained materials.

Leeb Hardness Tester NOVOTEST T-D2-R
Leeb Hardness Tester NOVOTEST T-D2-R is a special version of the dynamic hardness tester with a miniature probe. The device has all the functions necessary for operation and allows to perform rapid measurements of the hardness of metals to the operator without experience with similar equipment.
It is usually used for bulk products, has low requirements for the quality of the testeded surface, grain size and uniformity of materials.

UCI Probe Test Stand NOVOTEST
NOVOTEST UCI probe Test Stand is used to measure the hardness of superthin sheet products. It can be used with any UСI probes which are equipped with NOVOTEST hardness testers. The point is that the thin wall of the product, when the UCI probe indenter is indented into it, does not provide sufficient impedance (it deforms under the load of the probe). In order to compensate for this deformation, this device is used.

UCI Probe NOVOTEST U1
The UCI (ultrasonic contact impedance) sensor allows you to measure the hardness of small-sized products, with virtually no restrictions on weight and wall thickness, and also measure the hardness of surface hardened layers (30-40 μm thick).
As a consequence of the suitability of the method for measuring the hardness of products of any size, it is more universal than the dynamic one. However, there are some features – the ultrasonic hardness measurement method can give an increased spread when measuring the hardness of coarse-grained materials (cast iron, some stainless steels), as well as when measuring very soft materials – some non-ferrous metals.

UCI Probe NOVOTEST U2
New generation of ultrasonic contact impedance probe NOVOTEST UCI U2 for hardness testing.
In comparison with the previous version of the probe, the influence of the operator and measurement technique on the repeatability of results is significantly reduced. Any user without experience with such a device can do accurate measurements. And thanks to a special technology for fixing the change in the frequency of the indenter, the measurement accuracy is increased.

Support rings for Leeb probes
Support rings are essential accessories for Leeb hardness tester probes, particularly when testing cylindrical or spherical surfaces with diameters smaller than 50 mm. These rings ensure accurate and consistent measurements by providing a stable contact surface between the probe and the specimen. The support rings are designed to accommodate various outer and inner diameters, allowing precise hardness testing on both cylindrical and spherical specimens.
