Gas TensioMeter

The gas tension meter calculates the surface tension of a liquid by measuring the pressure changes during the formation of bubbles in the liquid. It is used for testing the wettability of coatings and inks, evaluating the liquid absorption of printing paper, and detecting the surface treatment effectiveness of plastic films.
Selection
Select the pressure range based on the viscosity of the liquid being measured, ensure the sample temperature matches the instrument's temperature control accuracy, confirm that the bubble generation rate complies with standard methods, check that the sensor range covers the expected tension values, and ensure the data interface is compatible with the existing recording system.
