A rockwell hardness tester for sale is an instrument that measures the stiffness or strength of a material by using a test method based on indentation. The tester forces a diamond indenter or steel ball into the material, and the size of the impression left on the surface is used to measure the hardness. Different testing methods exist, and the type of indenter selected will determine the results. The most common types of hardness tests are the Brinell, Rockwell, and Vickers methods. The test tool must be able to apply sufficient load to the material to cause deformation. A hardness tester can also be used to assess the strength of a coating or finish.
The Rockwell scale is the most common hardness testing system in the world. It uses a penetrating diamond cone or a penetrating steel ball to measure the hardness of metals and other materials. The test system measures the depth of the impression and the size of the indentation to produce a value that can be compared to other samples.
Allied offers a full range of Rockwell hardness testers for use in the laboratory and on the shop floor. Choose from a wide selection of models that use a diamond cone or steel ball indenter to evaluate a material according to the Rockwell Regular and Superficial scales. These hardness testers can be configured to support additional standardized testing systems including the Vickers and Brinell methods.
The Qualitest rockwell hardness tester range starts with low cost analog models and includes advanced digital portable devices that provide exceptional features like auto-probe detection, auto-direction detection and multi-point calibration. These units are the ideal choice for heat treat facilities, workshop and inspection labs. All Qualitest portable hardness testers are compatible with DiaMet software for a complete data management solution.
Whether you need a hardness tester to evaluate the quality of your metals, plastics or ceramics, we have a machine for you. We offer hardness testers for the Rockwell, Brinell, and Vickers testing methods as well as portable ultrasonic hardness testing instruments to evaluate samples on the go.
Benchtop hardness testers are large, heavy pieces of equipment that use the Brinell, Rockwell or Vickers testing methods. They are ideal for the lab because they are easy to operate and can handle large loads. Portable hardness testers, on the other hand, are much smaller and lighter. They are able to perform hardness tests on the shop floor without the need for a test bench, but they cannot accommodate the same variety of indenter sizes as larger machines.
