A rockwell hardness tester for sale is a piece of testing equipment that measures the hardness of metals and other materials by making an impression in the material. The depth of the impression is then used to determine the hardness number. There are several different types of hardness tests, including the Brinell test, the Rockwell test, and the Vickers test. Each type of hardness test has its own advantages and disadvantages.
The Rockwell method is the most popular. It uses a diamond cone or penetrating steel ball to make an impression in the material and then measures the size of the impression. This method is suitable for all metals, and it can be used on both flat and curved surfaces. It can also be used to measure the hardness of plastics and other non-metallic materials.
Brinell testing is another popular way to measure the hardness of metals. This method uses a spherical indenter to distribute the test load evenly across the surface of the sample, and it can be used on both rough and smooth samples. It is also more accurate than the Rockwell method, and it can be used to test all types of metals, from soft to hard.
Vickers testing is a microhardness testing method that can be used on both solid and metallic materials. This method can be used on both curved and straight surfaces, and it is particularly useful for measuring the hardness of thin sections of metal. It is also able to measure the hardness of soft metals, such as aluminum and cast iron.
Portable hardness testers are designed to be used on-site, away from the lab. These devices are lightweight, compact, and easy to use. They are available in both manual and automatic models, and they can be used to measure the hardness of a wide range of materials. They are typically used in manufacturing, quality control, and other industrial applications.
A digital Rockwell hardness tester for sale is a great choice for heat treat facilities, tool rooms, and laboratories. It offers a variety of features, including programmable scale conversions, dwell times, and statistical capabilities. It is capable of testing all regular Rockwell scales, as well as HB, HV, and HK. It is also equipped with a USB port for data storage and transfer. This device is also available with lifetime technical support from the manufacturer.
