A Quality Hardness Tester Ensures Accurate Material Testing

By Golden Pex Subscribe to RSS | December 15th 2011 | Views:

Hardness is defined by ability of a material to resist deformation. In the manufacturing industry, it is important to test the hardness of various types of materials—right from metals to plastics. A specially manufactured machine called a hardness tester is employed for this purpose. This machine helps apply a particular amount of pressure on the material and tests the amount of resistance shown by the material. The higher the resistance, the harder the material is believed to be.

Hence, material testing is an important part of any manufacturing process. The same time, it is an integral part of the quality testing and assurance process. A few years ago, these testers were bulky machines that were not very used friendly. However, with the advancement of technology, portable hardness testers that have easy-to use features and display screens have been developed. This has made the testing of materials far more easy and accurate.

Using hardness testers:

A hardness tester is used to measure the hardness as well as resistance of several materials such as metals, rubber, plastics, lead, soft films among other items. While it is easy to test the hardness of small objects or samples, the same is not true in the case of larger objects. That is why portable hardness tester are becoming popular. They can be used in different places and moved from one place of the factory to another. The type and brand of tester that you choose should depend on the materials that you want to test for hardness. For this purpose, you should ideally consult a manufacturer or dealer of such equipment.

Things to keep in mind while choosing a hardness tester:

The hardness testing machine should be replete with several latest features in order to carry out your testing tasks effectively. For instance, it should offer you a variety of scales that display the hardness values. It should also have certain preset functions for commonly tested materials (both metals and plastics). A good tester should also be able to offer you the best accuracy—right down till the last decimal. There are some testers that display the results in points, tenths and hundredths. In addition, a good tester should come with a due warranty and guarantee. This is the true mark of a quality product. In addition to all these material testing qualities, the tester should also be competitively priced.

If you keep these points in mind while purchasing a tester, you are more likely to make the right choice. It is important to check if a hardness tester has been manufactured in adherence to various industry standards such as ASTM e-18. Only then can you be assured of a dependable product.
