Rebound / Dynamic Hardness Tester
Impact beyond compare
Mobile Hardness Testing is becoming more and more important in all modern production processes, offering a quicker and above all an economical alternative to stationary hardness testing.
An impact body carrying a tungsten carbide ball at its tip is impelled against the test surface by spring force. Due to the impact and the plastic deformation of the surface resulting therefrom, the impact body loses a part of its original speed viz. the more, the lower the hardness of the material to be tested. The speeds before and after the impact are each measured in non-contact mode. The hardness value is calculated by the ratio of the impact and rebound speeds.
The lightweight, user-friendly Portable Hardness Tester Model DP 300 measures by the well accepted dynamic measurement principle for all metals with high accuracy and offers wide amplitude in the measurement scales/ranges. The instrument is offered with different impact devices to optimize it to specific jobs and test applications.
