The force exerted by a surface tension meter on the surface of a liquid to reduce its surface area is called liquid surface tension. The surface tension ceremony is a measuring instrument used to measure the surface tension value of liquids, based on principles such as platinum plate method, platinum ring method, bubble method, hanging drop method, droplet volume method, and heavy drop method. It can measure the surface tension value of liquids. Simultaneously utilizing software technology, measurable surface tension values that vary over time. A surface tension meter, also known as an interfacial tension meter, can measure both interfacial tension and surface tension. Methods for measuring surface tension, etc. Surface tension can be divided into several categories depending on the measurement method used:

Platinum Ring Method: First, gently immerse the platinum ring into the liquid, then slowly raise the platinum ring and lower the liquid level relative to it, so that the platinum ring forms a liquid column and separates from it. During the entire process, the platinum ring surface tension meter will measure a value, which is formed when the platinum ring liquid sample is detached but not detached. This value is converted into a surface tension value.

Platinum plate method: After immersing the platinum plate in a liquid, the surface tension around the platinum plate will be felt, 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 platinum plate will stop invading into the liquid. At this time, the balance sensor of the instrument will measure the depth of invasion and convert it into the surface tension value of the liquid.

Suspension drip method: When liquid drips from the dropper mouth, the size of the liquid is related to its density and surface tension, and the weight of the droplet is related to the radius of the dropper mouth and the surface tension of the liquid. This method measures surface tension based on the shape of the droplet. Calculate the surface tension based on the equation regarding capillary phenomenon.
