YY251D Leeb Hardness Tester Factory

I. Product Introduction

The Leeb hardness tester detects hardness based on the Leeb hardness measurement principle and

can measure the hardness of a variety of metal materials. The tester adopts advanced digital probe

technology, digital signal processing is done directly on the probe, which is not easily disturbed and

provides excellent testing accuracy. The probe has a built-in direction sensor, which automatically

compensates for the measurement error in different impact directions. The instrument has a variety of

built-in hardness systems, which can be converted between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA), Rockwell (HRB), Rockwell (HRC) and tensile strength (σb). The instrument

adopts an impact device D suitable for assessing the hardness of common metal materials.
