Uni-T Leeb UT347A Hardness TesterThe Uni-T Leeb UT347A Hardness Tester is a portable and accurate device for measuring hardness using the Leeb method, designed for field use and for testing large components such as turbines, pressure vessels, and shafts. It supports 6 hardness scales (HL, HB, HRC, HRB, HV, HS) and tensile strength, offers 5 impact directions, and features automatic probe recognition without calibration. Built-in memory for 900 data sets, a 640×480 camera, Bluetooth with a mobile app and PC software, and a thermal printer make it easy to record and analyze measurements. The entire unit is housed in a compact casing with a clear, 2.8″ color TFT screen and powered by a high-capacity battery.Measurement precision and flexibilityThe device works with various probe types (up to 7), allowing you to adapt them to the material and measurement conditions, while automatic probe identification eliminates the risk of errors during changes. Several operating modes—statistics, multi-unit, line graph, and histogram—translate into better quality control, as the user sees not only the result but also its distribution. Over-limit alarms and LED indicators help respond quickly to deviations.User-friendly operation and data managementThe UT347A offers Bluetooth and USB connectivity, making it easy to transfer results to an app or computer, while thermal printing allows you to generate a report on-site immediately. Adjustable backlighting, voice prompts, and an LED flashlight enhance comfort when working in challenging conditions. The 2500 mAh battery provides several hours of operation, and the auto-off feature helps conserve energy.Included Leeba UT347A Hardness Tester Type D impact probe Leeba hardness standard block Nylon brush USB-C cable User manual Downloadable guidelines Thermal printer paper x 2 Manufacturer Uni-T Model UT347A Hardness scales HL, HB, HRC, HRB, HV, HS Strength measurement σb (tensile strength) Impact angles 0°, 45°, 90°, 135°, 180° Measurement modes statistical, multi-unit, line graph, histogram Statistics max / min / avg Memory up to 900 data sets Camera 640×480 (up to 900 BMP images) Display 2.8″ TFT 320×240 Printing 57 mm thermal paper Connectivity Bluetooth (APP), USB, PC software Over-limit alarms yes (3-color LED) Backlight adjustable Voice prompts yes Power supply 3.7V 2500 mAh Li-Po battery Charging DC 5V 2A (USB-C), approx. 2–4 h Auto power off 1 / 5 / 10 / 30 min or off Drop test 1 m Certifications CE (pending), UKCA Materials supported steel, alloy steel, stainless steel, cast iron, aluminum, copper, and their alloys
