Hardness tester Portable hardness tester based on the Ultrasonic Contact Impedance (UCI)method, using a Vickers diamond indentor. The hardness value is electronically measured across the Vickers diamond indented surface and displayed instantly. Specially designed high-tech probes enables measurement on areas such as rotogravure cylinder (without any damage on surface) and in regions of restricted access, available as an optional accessory. The instrument allows for use in any directions with accuracy. Hardness measurements to standard scales of HB, HV, HRB & HRC. Technical parameter.
