Liquid Surface TensioMeter

The liquid surface tension meter quantifies the tendency of liquid surfaces to contract by measuring the intermolecular forces on the liquid surface, utilizing techniques such as the ring method or pendant drop method. It is used for testing ink adhesion, evaluating the leveling properties of coatings, and verifying the effectiveness of cleaning agents, providing data support for assessing print quality and the uniformity of plastic coatings.
Selection
When selecting, consider matching the liquid properties with the measurement method; viscous liquids are suitable for the pendant drop method. Verify that the measurement range covers the actual surface tension range, and for high-temperature samples, a heating stage accessory is required. Pay attention to the instrument calibration method; for contact measurement, ensure the cleanliness and maintenance of the platinum ring. For portability needs, a handheld model can be chosen, while for online monitoring, an automatic sampling model is recommended.
