AUH-III Ultrasonic Portable Hardness Tester
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 Brinell,
Rockwell and Vickers scales.
Ultrasonic hardness tester AUH-III 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 AUH-III 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.
Features:
l Perfect Accuracy——±3% HV, ±1.5HR, ±3%HB
l Microscopic Indentation—— Only high-power microscope can observe
the indentation
l Quick Measurement——Result in 2 seconds
l Large LCD Display——Directly display measurement result, times
count, maximum, minimal, average and deviation.
l Friendly Operation——Operate well after short training
l Promised Warranty——2-Year warranty for main unit (Excludes Probe)
l Mass Storage——Save 1000 groups measurement data
l Simple Calibration——Save 20 groups calibration data for invoking,
improve calibration efficiency.
