Ring Method Surface Tension Measurement Device

The surface tension meter using the ring method measures the maximum pulling force when a metal ring is detached from the liquid surface to calculate surface tension. It is used to evaluate the effectiveness of liquid surfactants and wetting properties, as well as to control product quality and printability in the coatings and inks industry.
Selection
When selecting, consider the sample viscosity range, and apply correction factors for high-viscosity liquids; pay attention to the corrosion resistance of the ring material, with platinum-iridium rings suitable for acid and alkali solutions; match the balance sensitivity, typically selecting 0.1 mN/m precision for routine measurements; ensure ambient temperature fluctuations are less than ±1℃.
