Combined Hardness Tester NOVOTEST T-UD3

The NOVOTEST T-UD3 Combined Hardness Tester is a portable instrument that combines Ultrasonic Contact Impedance (UCI) and Leeb hardness testing in one system. It is designed for industrial inspection applications where different component sizes, surface conditions and geometries require more than one hardness measurement method. Combining these two techniques allows qualified inspection personnel to select the appropriate method for the component being tested. The UCI method uses a diamond indenter and is suitable for measuring the hardness of small components, thin sections and surface-hardened layers where minimal indentation is important. The Leeb method uses a dynamic impact probe and is generally suited to sufficiently massive components, such as large forgings, castings and machinery parts. The T-UD3 supports a range of UCI test forces and Leeb probe configurations, including D, DC, DL, C, D+15, E and G types, subject to the supplied configuration. The instrument supports common hardness scales, including Vickers (HV), Brinell (HB), Rockwell (HRC) and Leeb (HL), with additional calibration options. Its measurement features include statistics, graph and histogram modes, measurement storage and data transfer. These functions can support quality-control documentation and help inspection teams maintain organised measurement records. For Indian manufacturers, fabrication companies, heat treatment facilities and third-party inspection agencies, the T-UD3 can be considered for applications involving different component geometries and material conditions. Before purchasing, buyers should assess the intended materials, minimum component thickness, surface condition, probe requirements and applicable inspection standards. The correct method and configuration are essential for obtaining meaningful measurements.
