The rockwell hardness tester for sale is an essential tool for a wide variety of industrial and commercial applications. These devices help manufacturers and other businesses test the hardness of metals, including steel and cast iron. The hardness of a material is determined by the amount of force needed to make an indentation into it. These tests are used for a number of purposes, from assessing the quality of raw materials to evaluating the durability of finished products. Choosing the right tool to measure metal hardness depends on the type of indentation you want to create. Penn Tool Co. offers a range of different types of metal hardness testing instruments, from simple analog models to advanced load-cell designs. Our comprehensive catalog features a variety of top brands in the industry, all available at an affordable price point.
We also carry the Wilson brand of hardness testers, a trusted name in the industry. The company has been manufacturing and engineering hardness testers for more than six decades, creating innovative solutions that are used across a variety of industries. Wilson hardness testers are highly regarded for their reliability, accuracy and ease of operation. Their durable and versatile models are available in many configurations, with options for measuring regular Rockwell and superficial Rockwell scales as well as Brinell and Vickers hardness tests.
If you’re looking for a high-quality digital model that can test in the regular Rockwell and superficial scales, we recommend our Qualitest, HardRocker or Rocky Series hardness testers. These advanced units feature a closed-loop electronic load measurement system and a large touchscreen for method set up and display. They can automatically adjust for various indenter sizes and loads, ensuring accurate and repeatable results. They can also calculate the hardness of your samples based on their depth of penetration, giving you an immediate and direct reading. They also include USB data storage for easy access to test results and reports.
The Brinell test is another popular way to measure metal hardness. It uses a steel ball indenter to mark the surface of the sample, which can produce more legible and accurate results than other methods. The spherical indenter distributes the test load evenly, and this helps prevent errors due to surface conditions or optical measurements. This technique is preferred for testing hard metals, but it can be used to evaluate softer metals as well.
Other testing techniques include the Knoop and Leebs methods. These are useful for testing small precision parts, thin materials, wires and case depth hardness, respectively. Other non-destructive testing methods include ultrasonic testing, which involves directing sound waves through the sample to identify defects within it. This can be done by immersion or contact, depending on the application.
