UNI-T UT347A Leeb hardness tester

The UNI-T Leeb UT347A is a portable hardness tester that measures hardness using the Leeb method, designed for field use on large components such as turbines, pressure vessels and shafts. It supports six hardness scales (HL, HB, HRC, HRB, HV, HS) as well as tensile strength, offers five impact directions, and detects the probe automatically without requiring calibration. Its built-in memory stores 900 data sets, and a thermal printer lets you produce a measurement report on site.

Measurement modes include statistics, multi-point readings, line chart and histogram, so you can see not only each result but also how the readings are distributed. Limit-exceeded alarms and LED indicators help you respond quickly to deviations. Bluetooth and USB connections make it easy to transfer results to an app or computer. The 2.8-inch colour TFT display, adjustable backlight and LED torch make the tester practical to use in poor lighting.
