Visual multifunctional surface 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 the liquid and gas phases as surface tension, such as20The surface tension of water at ℃ is72.75mN/mIt refers to the surface tension at the interface between water and air.

1Platinum Plate Method and Platinum Ring Method:

Platinum plate method: sampling period1-5Seconds are the most convenient for viscous liquids. When the platinum plate is immersed in the measured liquid, the surface tension around the platinum plate will be affected, and the surface tension of the liquid will pull the platinum plate down as much as possible. When the surface tension and other related forces of the liquid reach equilibrium with the equilibrium force, the sensing platinum plate will stop immersing into the interior of the liquid. At this point, the balance sensor of the instrument will measure the immersion depth and convert it into the surface tension value of the liquid.

Platinum Ring Method: Sampling Period50-200The fully automatic process can be divided into:（1）Gently immerse the platinum ring into the liquid; （2）Slowly lift the platinum ring upwards, causing the liquid level to relatively decrease, forming a liquid column below the platinum ring and ultimately separating from it. The platinum ring method is used to sense a maximum value, which is formed when the platinum ring is about to separate from the liquid sample but not yet. The accuracy of converting this highest value into surface tension value depends on the viscosity of the liquid.
