Useful Questions That You Should Ask Before Purchasing A Hardness Tester
Hardness testing is an important process in gauging the overall properties of a material
. This mechanical testdone with a hardness testeris usually employed to learn more about the flexibility, durability, strength, brittleness etc of a material. These findings prove to be very useful when it comes to the actual application of the material. Further, depending on the above mentioned parameters, the very composition and structure of the material can then be changed to make it better. Some historical records show that hardness testing is a method that has been used for nearly three centuries!*How is the material testing process carried out?
Since this process is all about testing the resistance of a particular material to pressure, this test requires an advanced machine. The material is placed on to an indenter of specific measurements. The material is placed here for a particular time and within this period; the dimensions and the indents on the material are measured. The final figures obtained by carrying out this process give a fair idea about the properties of the material. A calibration service is often coupled with this. Often, it is seen that the greater the hardness of an object, the better is its capability to resist friction or erosion caused by chemicals.
Now you know how this process is carried out and how it could benefit your industrial or manufacturing process. It is also important to know how to choose the right hardness tester .
Following are some important points to rise when you are purchasing a machine for testing hardness:
*What are the different hardness testing scales that your equipment can offer?
*Depending on the material you wish to test, is your hardness testing machine suitable for it?
*Does your testing machine allow for different sizes and shapes to be loaded onto the indenter?
*At any given point of time, what is the volume of testing that your machine can handle? At what point does the machine reach an overload?
*Does the machine you are choosing give you precise accuracy? In certain cases you might need passable accuracy, but in other cases you might need results to the last detail. Does your machine allow for these results?
*What is the return on investment that you can hope to get once you invest in your material testing equipment?
*What are the various models or hardness tester ranges available in your budget?
*What are the most common problems that have reported from your chosen model of a hardness testing machine?
*How high are the maintenance costs and how often will you have to service your hardness testing machines? Will calibration service be required?
*How easy is it to load and unload materials from the testing point?
By keeping these points in mind, you can easily hope to choose the best hardness tester that the market has to offer.
