Manual Ultrasonic Hardness Tester SU-100
SU-100 Introduction:
● At present, there are kinds of methods for hardness measurement,
commonly used like Brinell, Rockwell, Vickers, Leeb, etc. while the
disadvantages are obvious for the above hardness measurement.
● Rockwell and Brinell with heavy loading force and big
indentation, lead to serious destruction on sample surface.
● Vickers apply optical measurement, but only professional
technicians can operate smoothly, 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 SU-100 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 SU-100 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.
