Standard Leeb Hardness Test Block portable equipment

A standard Leeb hardness block is a precision calibration tool used to verify the accuracy and reliability of Leeb hardness testers. Whether it’s Rockwell, Brinell, Vickers, or Leeb hardness, all hardness calibration blocks are manufactured from high-quality materials, such as alloy or tool steel. These standard test blocks undergo strict quality control processes to ensure uniformity and consistency in hardness values. Each block is precisely calibrated and clearly marked with its corresponding hardness value in HL (Leeb hardness units), providing a reliable reference standard for portable testing instruments.
