LS252DL Handheld Digital Leeb Hardness Tester with DL Impact Device



The LS252DL Leeb Hardness Tester is an advanced, versatile device designed for precision testing in tight spaces such as grooves or gears. It features a DL impact device and utilizes cutting-edge dual coil technology, ensuring excellent repeatability and high accuracy. The built-in orientation sensor automatically compensates for measurement errors from different impact directions. This tester supports multiple hardness scales, including Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), and Rockwell (HRA/HRB/HRC), making it adaptable for various metal hardness testing requirements. Additionally, it offers a selection of metal materials to suit different testing needs, ensuring comprehensive and reliable results.
