LS256 Ultrasonic Hardness Tester
$430.00
The ultrasonic hardness tester adopts the UCI (Ultrasonic Contact Impedance) method to measure the
hardness of various metal materials. With its minimal indentation, it causes little to no damage to the
surface of the tested sample, making it ideal for applications where preserving surface integrity is
important. It is especially suitable for measuring the hardness of metal coatings, platings, and hardened
surface layers. The instrument supports multiple built-in hardness scales and allows automatic
conversion between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), and Rockwell scales, including
HRA, HRB, and HRC.
