洛氏硬度計
ZwickRoell洛氏硬度計可用於經典洛氏法、金屬上的表面洛氏法以及深度量測法，例如塑膠上的球壓痕測試。
With a Rockwell hardness tester, you can measure the residual indentation depth created by the indenter using a differential depth method. The deeper a defined indenter penetrates the surface of a specimen with a specified test load, the softer the material being tested. The most widely used Rockwell hardness test methods are standardized test methods on metals according to ASTM E18 and ISO 6508. In the plastics industry, these include the Rockwell hardness test to ISO 2039-2 and ASTM D785, as well as the ball indentation hardness test to ISO 2039-1.
Was zeichnet ein gutes Härteprüfgerät Rockwell aus?
A Rockwell hardness tester is designed to test the hardness of materials using the differential depth method.
A typical Rockwell hardness tester consists of a load application feature, an indenter, a test anvil and a measuring transducer. The DuraJet model is a software-controlled hardness testing machine with automatic load application through a closed control loop and fully automatic indentation evaluation. The N3 device works with a spring sleeve system.
With the software-controlled instruments you have access to a wide range of functions, including the use of templates, export of your results and much more.
The Rockwell hardness test has a variety of applications. It is not only used to determine material properties according to hardness and forming processes, but also for quick and effective testing in production and incoming goods departments. This helps ensure that the material meets specified requirements and will behave optimally when used for its intended application.
In the development of our ZwickRoell Rockwell hardness testers, we particularly take the following aspects into account:
- 高精度且耐用
- 容易且直覺化的操作，將操作錯誤降至最低
- 以未來導向的測試軟體
