Roller Ultrasonic Hardness Tester

Introduction Hardness tester is used to determine hardness of copper and chrome which painted on rotogravure cylinders with simple, fast and accurately method. Hardness test in Vickers have the advantage that are supposed to be non-destructive as the lasting surface indentation is microscopically small. Highlighting Characteristics: Perfect Accuracy——±3% HV, ±1.5HR, ±3%HB. Microscopic Indentation—— Only high-power microscope can observe the indentation. Quick Measurement—
