The Ultrasonic Contact Impedance (UCI) durometer PCE-3500 has been designed for the non-destructive hardness measurement of metallic components. A 136 Vickers diamond at the probe is stimulated with its self-resonance to allow the user to very accurately measure hardness of small items, thin-walled items (>1 mm), and surface-hardened layers. Small imprint after measuring for mirrored surfaces. - 50 Newtons UCI probe / 11.2 lbf force, 10 and 98 N probes are options - Tests HRC, HRB, HV, HB, MPa - Memory function via SD card and included PC software - Large color LCD display with back lighting
