A rockwell hardness tester for sale is a device used to measure the strength or stiffness of metal and other materials. It works by measuring the impression left on a sample surface by a harder tool, most often a diamond cone or steel ball. The test force is then measured to calculate the hardness. Different test methods exist, and each type has its advantages and disadvantages.
The Rockwell hardness tester is one of the most commonly used devices, and it can be used to measure a wide range of metal alloys. It uses a diamond indenter that is forced into the sample, and it can be calibrated to accurately calculate the hardness of a variety of scales.
Other testing devices include the Brinell and Vickers hardness testers. These use different methods to measure hardness, but both produce accurate results. The Brinell method measures the diameter of the impression made on the sample surface, and it is more accurate than the Rockwell method because the spherical indenter distributes the test load evenly.
It is important to choose a quality tester that fits the needs of your applications. Grainger offers a wide variety of models, including those that can measure the hardness of both large parts and small precision components. They also come in a range of capacities, from basic analog designs to advanced digital models with sophisticated load cell technology.
The Brinell and Rockwell testers can be calibrated to a variety of scales, and they are suitable for most metals. The Vickers hardness tester is another popular choice, and it can measure all of the standard Rockwell scales as well as HB, HV, HRD, HK and more. It is compatible with both Brinell and Rockwell indenters, and it can convert between them quickly and accurately.
Whether you need to test a single part or an entire batch, you can find a high-quality tester that will meet your needs at Grainger. Browse the selection of dependable analog and digital models, then select the model that best fits your application. You can even get a portable hardness tester that can help you test samples on the go, and it can be used with all of the most popular Rockwell, Brinell and Vickers methods. In addition, some of the models are designed to meet the demands of a variety of environments, from heat treat shops to tool rooms and inspection labs. This means you can get the precise measurements you need without breaking the bank.
