LS252DL is an integrated Hardness Tester. The instrument detects hardness based on the Leeb hardness measurement principle, and can measure the hardness of various metal materials. The instrument adopts DL impact device, which is suitable for testing on grooves or gears with narrow spaces. The instrument adopts excellent dual-coil technology, which has good repeatability and measurement accuracy. The probe has a built-in direction sensor, which automatically compensates the measurement error of different impact directions. The system has a variety of built-in hardness scales, including Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), Rockwell (HRA), Rockwell (HRB), Rockwell (HRC) Convert between each other to avoid tedious manual calculations.
The instrument adopts DL impact device, built-in a variety of metal materials can be selected, to meet the testing needs of different metal hardness.
