Kind of Hardness Tester
There are two main types of hardness testing tool – bench (stationary, classical) and portable (mobile, electronic).
Bench hardness tester – is the classical hardness tester which measures hardness by standard methods Brinell or Rockwell or Vickery or Shor and so on. As a rule, hardness tester name, including the title of the hardness scale. As an example, “Rockwell Bench hardness tester” and “Bench Brinell hardness tester”. There is some bench top hardness tester that allows the user to measure hardness not only by the scale, but also by the several large hardness scale. For example, there is a bench hardness tester that allows the user to measure hardness with Rockwell, Brinell and Vickers scale. All Bench hardness testers are large and heavy (over 50 kg), these units also must be mounted on a table or on the floor. The main advantage of such devices – is the implementation of the classical model, the direct method of measuring the hardness.
Portable hardness tester – as opposed to bench hardness tester, this instrument has a small size, light weight, and they are compact devices that measure hardness with some scale violence. Typically, modern portable hardness testers can measure the hardness of all scale violence. Advantages of portable hardness testers is to enable users to take the device and with it to measure samples. You do not need to take the sample into the workshop.
Portable hardness measuring instrument – is an electronic device, so they usually have a set of useful features-users can save the measurement results in internal storage, after which the results can be sent to a computer to create reports in a special program ARM control, which is provided with a portable hardness testers, portable hardness testers – in contrast to bench hardness testers, it has some advantages, but there are some cases, when they can be solved only by a bench hardness tester. However, such cases are very rare, and we can say that in 99 cases out of 100, the user can use the portable device.
As a rule, the most useful and easy to carry is a portable device. That is why it is the best solution.
