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.

When selecting a hardness tester for your application, it is important for you to consider the following:

A, Choose the correct test method based on the application.
Plan to use the highest test force and largest indenter possible. Consider the effects of the shape and dimensions of your test sample.

B, 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.
 
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?

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.
