Conform standard ASTM-A1038-05 DIN 50159-1, JB/T9377-2010 Introduction: • At present, there are kinds of methods for hardness measurement, commonly used like Brined, Rockwell, Vickers, Leeb, etc. while the disadvantages are obvious for above hardness measurement. • Rockwell and Brinell with heavy loading force and big indentation, lead to serious destructive on sample surface. • Vickers apply optical measurement, but only professional technicians can smoothly operate, impossible to measure hardness of heavy work piece, installed machinery and permanently assembled parts. • Leeb hardness tester apply rebound and indirect method to measure hardness, easily lead to big deviation when convert to Birnell, Rockwell and Vickers scales. • Ultrasonic hardness tester KU100 apply ultrasonic contact impedance method to do comparative hardness measurement for testing pieces, with advantages of high accuracy, efficiency, portable and easy operation. • Ultrasonic hardness tester KU100 is widely used to measure hardness of small forgings, cast material, weld inspection, heat affected zone, Ion-nitrided stamping dies and molds, forms, presses, thin walled parts, bearings, tooth flanks, etc.

• Small Indentation-Only high-power microscope can observe the indentation • Efficient Measurement-Result In 2 Seconds • Large LCD-Directly display measurement result, times count, Maximum, Minimal, Average and deviation. • Easy Operation-Operate well after Short training • High performance-2-Year Warranty for Main Unit (Excludes Probe) • Mass Storage-Save 2000 groups measurement data • Simple Calibration-Save 20 groups calibration data for invoking, improve calibration efficiency.
