Half automatic hardness tester except loading initial force and change force knob. Operation is very convenient and fast.
Color touch screen, displays loading force, indenter type, dwell time, and conversion scale.
Motorized control loading, dwell and unloading, eliminates error by manual operation.
Built-in micro processor auto compute max, min, mean and deviation value, resolution is 0.1HR, largely improve accuracy.
Auto hardness conversion to others scales, no need to check table and improve working efficiency.
Support Multiple languages, English, Turkish, German, etc. Convenient for local customers operation.
Save 2000 single testing results and 1000 group results for reviewing and analysis
Optional blue tooth mini printer is available.
Application:
Rockwell B Scale HRB: Copper alloys, soft steels, aluminum alloys, malleable iron, etc.
Rockwell C Scale HRC: Steel, hard cast irons, pearlitic malleable iron, titanium, deep case
Hardened steel, and other materials harder than B100.
Rockwell A Scale HRA: Cemented carbides, thin steel, and shallow case-hardened steel.
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.
