NOVOTEST Leeb Hardness Tester 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.

The main advantages

Scales and materials

The device comes with preliminary calibrations for various scales and materials, which makes the device universal.

SCALES: HRC, HRB, HB, HV, HL, MPa.

MATERIALS: steel, alloy steel, cast iron, stainless steel, aluminum, bronze, brass, copper.

It also can be calibrated for any scale and materials (USER scale).

Low requirement for surface quality and structure of materials

The Leeb Hardness Tester NOVOTEST T-D3 can be used for products with a poorly prepared surface (roughness 3.2 Ra and more), as well as for materials with a coarse-grained structure, such as cast iron and others.

Various probes types

The Leeb Hardness Tester NOVOTEST T-D3 can be used with various types of probes depending on the task and scope.
