Rockwell Hardness DL

The Leeb hardness DL calculates hardness values by converting the ratio of the rebound velocity to the impact velocity of an impact body striking the material surface. It is used for rapid on-site hardness testing of metal materials, capable of testing large workpieces and in multiple directions.
Selection
When selecting, consider that the material thickness meets the minimum requirement, the curvature of the test surface falls within the probe’s adaptation range, and the material hardness value is within the instrument’s measurement range. Choose the corresponding impact device based on the material’s elastic modulus, and verify the validity of the instrument’s calibration certificate.
