Product Description
Ultrasonic Hardness Tester SU-300
Product Description:

High Measurement Accuracy - ± 3% HV, ± 1.5HR, ± 3%HB;

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 1000 groups measurement data;

Simple Calibration - Save 20 groups calibration data for invoking, improve calibration efficiency.


SU-300 Application Range:


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 SU300 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 SU300 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.
