On Site Hardness Testing

MIC 10 Hardness test is one of the quickest and convenient portable method to determine the hardness of a material on-site. The method of this hardness test is according to the UCI Method (Ultrasonic Contact Impedance). The hardness is measured by detecting the frequency shift of a longitudinal oscillating rod with a Vickers diamond indenter. The diagonal of the indentation is not optically measured, as is usually done, instead the indentation area is electronically detected by measuring the frequency shift. The shift is proportional to the size of the Vickers indentation. The MIC 10 operates according to the Ultrasonic Contact Impedance (UCI) method of hardness testing, and is standardized according to ASTM A1038. MIC 10 probes use a Vickers diamond indenter that gives you the precision to position it on a tiny point. Indentations produced by the MIC-10 are much smaller than equivalent Rockwell indentations, making this one of the least destructive portable hardness testers available.
