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.



NOVOTEST Lab is your real laboratory in your pocket! Optionally with T-D2 (Lab) model only!

The results of measurement, adjustment and calibration of the coating thickness gauge in smartphone – the innovative NOVOTEST application for smartphones based on Android.

The functions of devices have no been so wide before! With the Bluetooth connection, your smartphone is able to control all the functionality of the NOVOTEST coating thickness gauge without wires. The intuitive interface of the application itself, access to the Internet, mail and instant messengers, touch screen, camera, microphone and GPS receiver of the mobile device make the use of NOVOTEST devices much more convenient and versatile.

– the ability to store archives of other devices with Bluetooth in one application.


The main advantages of the Leeb Hardness Tester NOVOTEST T-D2:


The Leeb Hardness Tester NOVOTEST T-D2 is calibrated to measure the hardness of steels, cast iron, stainless steels, aluminum on all major scales – Rockwell, Brinell and Vickers. And also the hardness tester allows user to evaluate the tensile strength. If necessary, the user can create additional calibration for any scale and material.

The Leeb method allows user to measure the hardness of products with a poorly prepared surface (roughness up to 3,2 Ra), as well as coarse-grained materials such as cast iron, etc. However, it must be noted that the dynamic method without additional measures allows to test the hardness of only sufficiently massive products (weight over 5 kg, wall thickness at the measurement site more than 10 mm).


Shock-resistant, rugged housing with a silicone protective bumper cover allows the hardness tester to be made shockproof. The indicator of the device is clearly visible in the sun, when used in the dark – it has a display backlight with adjustable backlight. The hardness tester can be used both in the cold (up to -25 ‎°C), and in conditions of high temperatures. Thus, user can measure hardness in the most severe conditions without worrying that the device can let him down.

If necessary, the device can be equipped with a probes of various types to solve various tasks of hardness measuring.
