Global Hengda surface tension meter

Global Hengda Interface Tension Meter: The force generated at the interface between a liquid and another immiscible liquid is called the interfacial tension between the liquid phase and the liquid phase; Meanwhile, we usually refer to the tension between liquid and gas phases as surface tension. For example, at 20 ℃, the surface tension of water is 72.75mN/m, which refers to the surface tension at the interface between water and air.

　　1Introduction

　　Regarding the table/interface tension meter

The force generated at the interface between a liquid and another immiscible liquid is called the interfacial tension between the liquid phase and the liquid phase; Meanwhile, we usually refer to the tension between liquid and gas phases as surface tension. For example, at 20 ℃, the surface tension of water is 72.75mN/m, which refers to the surface tension at the interface between water and air.

The fully automatic surface tension meter can measure both adhesion force and surface tension. The surface tension meter adopts the platinum plate method and platinum ring method commonly used in production practice.
