Novotest T-D3

The Leeb method is the most popular portable method for testing metal hardness using a Leeb hardness tester. The tester uses a dynamic method that is easy to use as it requires no special skills - the user simply charges the probe, places it on the surface, presses a button and the hardness value is displayed. This method can test both large and small metal parts. The Leeb hardness tester measures hardness scales for steel and other metals and allows for custom calibrations and additional languages.

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.
