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.
