The Uni-T UT347A digital hardness tester measures hardness on the Leeb scale and automatically converts readings to the HL, HB, HRC, HRB, HV and HS scales. It supports automatic impact device recognition without calibration and offers four measurement modes: statistics, multiple units, line chart and histogram.
The 2.8-inch color TFT screen has a resolution of 320 × 240 pixels, while the 640 × 480-pixel camera helps document measurements. The internal memory stores up to 900 data sets, which can be printed using the built-in thermal printer or transferred via Bluetooth, USB-C and the Smart Report-Hardness Tester app.
