Combined Hardness Tester NOVOTEST T-UD2

The Combined Hardness Tester NOVOTEST T-UD2 combines the advantages of two methods: UСI  (ASTM A1038) and Leeb (ASTM A956), which makes it possible to solve almost any task of operational hardness testing. With this device, the user will be able to measure the hardness of both a large products with a rough surface and a small samples of complex shape and with a thin wall.

This modification of the device has all functions for working with various materials and scales, which makes it an optimal device for non-destructive testing of metal hardness.



Innovation! NOVOTEST Lab is your real laboratory in your pocket! Optionally with T-UD2 (Lab) model only!

Do hardness measurements, calibrate the device, set up a convenient display of values, save the results of hardness measurements, synchronize the archive with your other devices and a PC, transfer measurement results to your colleagues – all this is available with your smartphone thanks to the special NOVOTEST app for Android.

Hardness testers have never had such opportunities! Using a Bluetooth connection, your smartphone connects to the hardness tester and you have a completely new device – a new generation hardness tester! The intuitive interface, ample opportunities for documenting results, Internet access, touch screen, camera, microphone and GPS receiver of a smartphone turn your hardness tester into something completely unique and previously inaccessible.

With NOVOTEST App you are able:

– setting and calibration of the hardness tester;

– display of measurement results in real time in numerical form with the construction of a graph, histogram or statistics;

– take a picture of the test object with the puting of hardness marks;

creation of a video of the controlled product;

– recording audio notes fro the tested object;

– automatic saving of measurement geolocation on Google maps;

– displaying a Google map with markers of places of measurements made on it and the ability to view these measurements;

– displaying the calendar of measurements (presentation of the archive in the form of measurements grouped by date);

– formation of the final comprehensive report on the measurement;

– sending a finished report to e-mail, messenger (or in any convenient way) directly from the application;

– flexible structure of the archive of measurements – completely similar to the usual explorer, with the ability to create folders and files with any names;

– synchronization with PC and other smartphones;

– cloud service for storing the archive of measurements;

– automatic and manual synchronization of cloud measurement archives between devices;

– launching the Google navigation mode, building a route and accompanying to the point at which the measurements were made

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


The main advantages of the Combined Hardness Tester NOVOTEST T-UD2 are:


Using a dynamic (Leeb) probe, it is possible to measure various materials different from their properties from steel without additional calibration, because by default, the device has built-in calibrations for different materials for the main hardness scales.

The dynamic measurement method is less demanding on the uniformity of materials and surface roughness, which allows the user to measure the hardness of a wide range of alloys, as well as to test products without first preparing the surface of the testing area.


Using the Ultrasonic Contact Impedance (UCI) method, the Combined Hardness Tester NOVOTEST T-UD2 can measure products with wall thicknesses of 1 mm or even thinner when using a UCI Probe Test Stand NOVOTEST.

The UCI probe allows measurements of products from 100g without additional manipulations, and even less when fixing samples in a vice or special equipment.


Due to the small contact area of ​​measurement, with an ultrasonic (UCI) probe it is possible to measure the hardness of products in grooves, gear teeth, and using a special nozzle it becomes possible to accurately measure the hardness of radius surfaces and even the wire hardness.

The ultrasonic (UCI) probe has an imprint almost invisible to the naked eye, to minimize the destruction aftertesting, the device can be equipped with a special probe with reduced load force (10N), which makes the measurement as non-destructive as possible.


The device comes in a protective silicone cover, which makes body shockproof and prevents the failure of the device after falls. Also, the device is tolerant of extreme operating conditions (the temperature range from -20 to + 40 C°)
