Choosing a Rockwell Hardness Tester for Sale

A rockwell hardness tester for sale is vital for a variety of industrial and commercial applications, allowing users to accurately determine the strength and stiffness of metal. These handheld instruments measure the resistance of a material to deformation by applying a force that creates an indentation in the surface. These tests are conducted using a range of different testing methods, including the Brinell and Rockwell scales. These devices can also be used to test nonmetallic materials, such as plastics and rubbers.

Depending on your needs, you can choose from a number of models that vary in size and scope. You can find compact digital portable hardness testers, large-scale floor-mounted units and dedicated testers that are integrated into production lines. Our selection of Rockwell and Brinell testers includes a wide range of indenter sizes and loads to help you select the best one for your application.

The Rockwell tester uses a diamond indenter to make an impression in the sample’s surface. It measures the depth of the indentation to calculate a hardness value, and can be converted to other scales such as HB, HV, and HK. The tester can be used on a variety of metals, including carbon and alloy steels, cast iron and nonferrous alloys. It can also be used on soft materials such as engineering plastics and elastomers.

Another popular hardness testing method is the Brinell technique, which utilizes a steel ball to mark the sample’s surface. The test results are more accurate than those from the Rockwell test, because the spherical indenter distributes the load evenly across the surface of the sample. This method requires the samples to be well prepared, and it can produce more errors than other tests because the impressions are difficult to measure.

You can also use the Vickers microhardness testing method to test a variety of solid and metallic materials. This method measures the diameter of an indentation, and it can be applied to both flat and cylindrical surfaces. This system can be used to test a wide variety of solid and metallic materials, but it is less useful for determining the hardness of softer metals, such as aluminum or titanium.

You can also use a Qualitest rockwell hardness tester, which is designed to quickly and easily convert between the regular and superficial Rockwell scales. This state-of-the-art portable device has a clean crisp display, auto probe detection and direction detector, and multiple load configurations. It can be configured to test the full range of regular Rockwell scales, as well as Brinell and Vickers.
