Combined Hardness Tester Novotest T-UD3 LAB


The device operates with both UCI (Ultrasonic Contact Impedance) and Leeb (dynamic) probes. User get the benefits of two methods of measurement – it is the maximum that can be obtained from portable hardness tester.UCI method for the hardness testing

The ultrasonic contact impedance (UCI) probe is used for measuring the hardness of small items, objects with a thin wall, complex form, and to measure the hardness of surface hardened layers.

Universal portable hardness tester T-UD3 LAB use the UCI method for the hardness measuring, which is standardized according to ASTM A 1038. This method allows user to measure very fast and easy: install the probe on tested object, press on the probe with required effort and after that save the results of the hardness value, which are showed on the display of the device. Diamond indenter has a small size that allows user to measure hardness value of all samples, which are thicker than 1 mm. The UCI method of hardness testing is the least destructive method because the hardness tester T-UD3 leaves much smaller stamps than leaves the bench hardness tester. That’s why portable hardness tester T-UD3 is very useful and universal.


Leeb method for the hardness testing

Leeb probe is used for measuring the hardness of non-ferrous metals, cast iron, coarse-grained materials, massive products etc.

Hardness tester T-UD3 LAB also use a dynamic method of the hardness measuring – Leeb method, which is standardized according to ASTM A956. This method allows user to measure very fast and easy: install the probe, press on the probe to recharge spring, press the button on the top of the probe to make test and after that save the results of the hardness value, which are showed on the display of the device. This method is used for measuring the hardness value of non-ferrous metals, cast iron, coarse-grained materials, massive products etc. (with weigh more than 5 kg or thicker than 10 mm) also this method perfectly complements the UCI method of hardness measuring. Hardness tester T-UD3 makes automatic calculation of the hardness of a wide range of materials – steel, stainless steel, cast iron, bronze, aluminum, so that we can say that combined hardness testers is the most universal, which is needn’t in recalibration, and fully ready for operation after “getting out of the box”.


During the hardness testing, user can take a picture of the sample and print the results of hardness measurements on some place on the photo of sample.

Saved results of measurements in the device can be transmitted to a PC for creating a report of testing in a specialized program – “ARM”, which supplied with the hardness tester.

Hardness tester allows user to measure the hardness at extremely low temperatures. The real tests has been carried out at a temperature of 25°C below zero. The device is operated very easy, the measurement accuracy did not exceed the value according to standards, keyboard and display of the device allowed user to operate confidently – the difference between the operating at the indoor temperature and operating at the extreme cold was not noticeable at all!

We have the CE certificate of conformity for Portable Combined Hardness Tester NOVOTEST T-UD3 LAB.

Delivery normally 14 – 21 days from receipt of payment
