Vexus MHV-1000Z is focus on the vickers testing under the small force, and mainly applicable to measure the hardness value of ferrous metals and non ferrous metals.

Vexus MHV-1000Z Series equipped with a LCD screen, the operation is more directly and clearly.

Vexus MHV-1000Z Series can display the measuring methods, testing force, indentation length, hardness
Value, dwell time of the testing force as well as the number of measurement.

Vexus MHV-1000Z Series can save and revise the date, record the measuring results, compute the data, output the information with the printer,

Vexus MHV-1000Z Series hardness conversion among 4 hardness scales, and linking to PC in RS 232 interface and cable.

Vexus MHV-1000Z Series adopt the design of double indenters, it equips with HV and HK indenter together, It is more suitable to measure the hardness of IC thin sections, coatings, ply metals; Glass, ceramics, agate, precious stones and other brittle and hard material.
 

The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a load of 1 to 100 kgf. The full load is normally applied for 10 to 15 seconds.

The two diagonals of the indentation left in the surface of the material after removal of the load are measured using a microscope and their average calculated. The area of the sloping surface of the indentation is calculated. The Vickers hardness is the quotient obtained by dividing the kgf load by the square mm area of indentation.

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.
