BEIJING UNITED TEST CO.,LTD. y UnitedTestDunouy Ring Method Tensiometer Model: TEN202 Surface / Interfacial tensiometer potential tension in the vadose zone, works, electric power department; or engineering, science academy. to determine W3ter (soil moisture) materials in irrigation petroleum, chemical Surface tension: To measure the surface tension between a liquid and the air, duNouy ring is placed below the surface of the liquid. This test is performed by pulling through the surface of the liquid. The force needed for the ring to break the surface (ov surface tension) is determined. Interfacial tension: 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 floating liquid to the greater density liquid is measured by 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.
