86256 Ultrasonic Hardness Tester
The 86256 ultrasonic hardness tester utilizes the ultrasonic contact impedance method to measure various metal materials. With minimal surface damage, it is ideal for testing metal coatings, plating, and hardened layers. It supports multiple hardness scales, including HL, HV, HB, HS, HRA, HRB, and HRC.
Core Advantages
