Rotating Ring TensioMeter

The rotational surface Tensiometer rotates the sample container via a motor, measures the changes in the liquid surface shape formed under centrifugal force, and calculates the surface tension value. It is used to detect the surface characteristics of liquids such as coatings and inks, guiding formulation adjustments and process control.
Selection
When selecting, consider measurement accuracy and speed range to match the sample's viscosity characteristics. Focus on temperature control stability to ensure data repeatability.
