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.
