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?

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.
