Leeb High Precision Hardness Tester, Metal Hardness Testing Kit, 360° Portable Digital Hardness Tester, 7 Units: HLD HB HV HS HRA HRB HRC

General Description

The portable digital hardness tester is a high-precision measuring instrument designed for testing the hardness of metals. Featuring a clear 128×64-dot industrial LCD screen, it can display 7 types of hardness values ​​(HLD, HB, HV, HS, HRA, HRB, HRC) with a simple operation, offering great versatility.   Made of ABS, it is lightweight and robust, capable of measuring hardness in various orientations (vertically downwards, inclined downwards, horizontally, inclined upwards, vertically upwards). It includes a data saving function for easy recording and review of measurements, as well as an automatic shut-off function after 10 minutes to conserve power.   With high accuracy (measurement error ≤±6% for HLD=800, display repeatability of 0.8%), it is suitable for a wide range of applications, including in the manufacturing, metal, chemical, and commercial industries. It is easy to use, supports sieved materials, and allows direct reading of the HB value during testing with a Type D impact tester, eliminating the need for manual tables.
