The Surface Tensiometer / Interfacial Tensiometer is used to test the liquids surface or interfacial tension, it’s kind of common general lab testing equipment, it’s widely used in various industries.


Pt ring test principle

Manual sample stage lifting

Peak value auto maintain

Onekey operation full scale reset, zero point stable and no drift

Full scale automatic calibration

Can test multi kinds of liquid interfacial tension value, such as oil / water;

Independent work, no need any auxiliary equipment

RS232C interface
