A rockwell hardness tester for sale is a device used to measure the stiffness of a material. This is accomplished by using a diamond cone or steel ball that makes an impression on the material and then measuring the depth of this impression. Different test methods are used depending on the type of material and the desired outcome. This guide will present the various hardness testing methods available and help you select the one that best suits your needs.
The Rockwell hardness tester is the most popular method of hardness testing for metals, plastics and engineering materials. It measures the penetration of a hard indenter, usually a diamond or a steel cone, into the test specimen and then compares this to a preload. It produces a hardness reading which is then converted into the relevant Rockwell scale (Rockwell Regular, Superficial or Twin) by using the appropriate formula.
Rockwell hardness testers are typically built to withstand heavy loads and can be used for both production and in-house testing. They are usually capable of producing a wide range of hardness tests for all common metallic materials and can be easily modified to perform other tests as required. They also provide a simple way to measure surface hardness on small, precision parts.
There are many models of portable Rockwell hardness testers available to meet your testing requirements. These include a full range of configurations for the most popular regular and superficial Rockwell hardness tests. Some are also able to perform the full Brinell and Vickers tests as well.
This hardness tester is suitable for use with most hard metals including cast iron and steel, as well as a variety of engineering plastics. It is easy to set up and operate, with a clear and crisp digital display. It features auto-probe detection, automatic direction determination and multiple methods for operation including manual and auto-probe load/unload and single and multi-point calibration.
It is designed to provide a quick and accurate hardness result for all common metal alloys, including carbon steel, forged steel, aluminium, stainless steel and more. The HM-200 is capable of performing all standard HB, HV, HRD and HK Rockwell tests as well as several other standard scales. It is fully adjustable and can be fitted with either a diamond or steel indenter for the most precise results possible.
