Product Details

Product Description

DHBRV-250T Universal Hardness Tester has already upgraded with Touch Screen, it is the state-of-the-art automatically hardness testing equipment specially designed for improving the working efficiency of our customers as its automatically design. After adjusting the focal length, the objective lens and indenter can be switched automatically. And the testing force can load, dwell and unload automatically. Then the objective lens will automatically return to the initial focus state, and the length of indentation can be measured directly.

Using Scopes:
Surface hardened steel, hardened steel, alloy steel, various QT and annealed steel,non-ferrous metal, hardened steel sheet, also suitable for soft metals, surface treatment metals and chemical processing metals.
