UCI Hardness Tester T-U3

Product Description

The most popular portable hardness tester in the world is the Leeb hardness tester, however, there are tasks that using this method is very difficult or even impossible to solve. This is due to the physics of the method, which assumes the massiveness of the testing object, to ensure the inertness of the product when the Leebs impact body hits the surface with a given force. In order to solve a wider range of tasks on the rapid measurement of metal hardness, our company offers hardness testers that implement the method of ultrasonic contact impedance (UCI) in accordance with ASTM A1038. A vibrating rod (mechanical resonator) with a diamond tip acts as an indenter in these devices, when it indent into the material, the base frequency of the resonator changes, on the basis of which the hardness is calculated. This method has proven itself around the world and has been used in industry for over 50 years.

Efficient Hardness Testing for Industrial Use

Engineered for reliability, the UCI Hardness Tester T-U3 supports rapid and precise measurements on metal surfaces. Immediate response time and internal data storage streamline the testing process in manufacturing and quality control settings. Its manual operation mode provides flexibility, while the intuitive LCD interface ensures clear readings. Suitable for portable fieldwork or in-plant inspections, it meets international hardness testing standards.


Versatile Measurements and Direct Conversion

This device covers a broad measuring range (250950 HV, 2070 HRC, 85650 HB), enabling effortless switching between Vickers, Rockwell, and Brinell scales. The direct conversion and high accuracy (3% of reading) make it an indispensable tool for engineers, technicians, and inspectors seeking dependable results without lengthy calculations.


Designed for User Convenience and Durability

Lightweight at just 0.3 kg, the T-U3 is genuinely portable yet robustoptimally sized for one-handed operation. User calibration, a multi-language display, and a user-friendly interface ensure seamless operation in diverse settings. With up to 20-hour battery life and easy USB data output, this tester delivers consistent performance wherever metal hardness needs verification.
