Product Description

Ultrasonic Hardness Testing apply UCI method: Ultrasonic Contact Impedance, a hardness testing method developed by Dr. Claus Kleesattel in 1961 based on the measurement of the frequency shift of a resonating rod caused by the essentially elastic nature of the finite area of contact between the indenter and the test piece during the penetration, the execute standard is ASTM A1038.

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, Max, Min, 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, presses, thin walled parts, bearings, tooth flanks, etc.

When selecting a hardness tester for your application, it is important for you to consider the following: Choose the correct test method based on the application.

Answer these key questions:
1, What kind of hardness scale to be used?
2, What is the material to be tested, and is this material suitable to the type of test method you are considering?
3, How large is the part, component or specimen to be tested?
4, Is the test point difficult to reach?
5, What is the quantity of testing that will be done?
6, How accurate does your test result need to be?
7, What is your budget?
8, What is the required return on investment and do you have ways to measure reductions in costs- yields, throughput, operator efficiency?
9, What testing problems have you experienced in your current method?
10, How knowledgeable are the users of the tester?

Verify the test results meet your requirements for accuracy and repeatability.
There are significant differences between levels of performance within each classification of tester. A difficult job on one tester could be very simple and fast on another.

So, although hardness testers within a test method and classification look alike, there are many features that can significantly affect productivity and accuracy. A good example of features affecting performance is demonstrated in bench Rockwell hardness testing systems.

All can handle moderately long parts using larger anvils or jack rests, however the portable type can usually test large parts more quickly and accurately, when compared to other bench testers, which require external support stands or fixtures. The SHR150 series, on the other hand, is much easier to use on small, awkward parts.
