A rockwell hardness tester for sale is a piece of equipment that uses a diamond indenter or steel ball to measure the strength of metals. The hardness of a material is based on the force required to make an impression in it, with higher numbers indicating harder materials. This type of equipment can be used for both laboratory and field use and can be found in a wide range of shapes, sizes, and capacities. From traditional bench-top devices that utilize the Brinell, Rockwell, and Vickers methods to portable digital ultrasonic machines for non-destructive evaluations on the go, this article presents a complete selection of hardness testers to fit your needs.
The most common method of measuring the hardness of a workpiece is the Rockwell test. This method uses a load of a specified amount of kilograms to press a diamond indenter into the sample, and then measures the depth of the indentation that is left behind on the surface of the sample. The harder the material, the deeper the indentation. The Rockwell scale includes nine levels that vary from soft metals such as copper to forged steel.
In addition to standard Rockwell scales, this hardness tester can also be set to test for HB, HV, HH, and HK. Its advanced digital display features programmable scale conversions, dwell times, and statistical capabilities. The unit automatically loads and unloads the indenter, and has a USB port for data output.
This device is suitable for testing metal alloys including carbon steel, cast iron, and non-ferrous metals. It also allows you to test engineering plastics and can be used in both laboratory and field testing. Its micro computer controlled touch screen offers a high-resolution display and USB output for data storage. This machine has a wide measuring range and can perform multiple tests at once, which makes it ideal for high volume testing.
The Phase II digital portable hardness tester is a state-of-the-art device that can be utilized in a variety of applications such as heat treat facilities, tool rooms, and inspection labs. It is easy to operate and delivers a level of dynamic precision not seen in other models. This rugged performer can handle a range of sizes and features an auto-probe detection, auto direction detector, a clear crisp display, and USB output and input. This model is able to perform tests for all the regular Rockwell scales as well as Brinell and Vickers. It is available in both manual and semi-automatic versions.
