Uni-T Leeb UT347A is a portable hardness tester for fast and accurate Leeb hardness measurements in the field and in production. It offers 6 hardness scales (HL, HB, HRC, HRB, HV, HS), tensile strength calculation, 5 impact directions, automatic probe recognition without calibration, and convenient saving and sharing of results via Bluetooth/USB, including thermal printing.
The Uni-T Leeb UT347A hardness tester is designed for quality control and inspection of large or hard-to-access parts such as turbines, pressure vessels, or shafts. Thanks to support for multiple probe types (up to 7), it easily adapts to the material and measurement conditions, and automatic probe identification reduces the risk of errors when changing accessories.
For better evaluation it offers several display modes and statistics (max/min/average). A limit exceedance alarm with a 3-color LED indicator helps you react immediately to deviations. Built-in memory for up to 900 data sets, an integrated camera (up to 900 photos), and connectivity via Bluetooth and USB make documentation and subsequent analysis in the app or PC software easier.
