The JZHY-180 Interface Tensiometer/Surface Tensiometer/Dunouy Tensiometer is an ideal instrument for measuring liquid surface tension. It is widely applied to inspect insulation oil materials in water conservancy and electric power departments, as well as for research and educational purposes in petroleum, chemical engineering, and scientific institutions. This tensiometer complies with standards ISO 1409, ASTM D1417, and ISO 6295.

Its main components include a platinum ring, platinum torsional wire, bracket, lever rack, and worm wheel.
Featuring a compact design with light weight, it ensures easy mobility and operation.
The manual operation is paired with dial display for straightforward tension value reading.
