Du Noüy ring method

Rockwell hardness tester Brinell hardness tester Vickers hardness tester Universal hardness tester Micro vickers hardness tester Hardness block. To measure the surface tension between a liquid and the air, the Tensiometer duNouy ring is placed below the surface of the liquid.

This test is performed by pulling the ring upward through the surface of the liquid. The force needed for the ring to break the surface overcome the surface tension is determined.


Du Noüy ring method – Wikipedia

There are applications where the surface tension at the boundary of two liquids needs to be measured. This is called interfacial surface tension.

The Tensiometer for this test needs to pull the ring up through the boundary between the lower, higher density liquid, and the liquid that is floating above. The force needed to break through the surface of the higher density liquid is recorded as interfacial surface tension.

The force needed to break the boundary going from the ttensiometer liquid to the greater density liquid is measured tensiomeger pushing the ring down through the boundary.

Du Nouy ring method: The du Nouy ring method is one technique by which the surface tension of a liquid can be measured. The method involves slowly lifting a ring, often made of platinum, from the surface of a liquid. The force required to raise the ring from the liquid’s surface is measured and related to the liquid’s surface tension. Item Quantity Frame 1 set Platinum ring R9.
