Dynamic Tensiometric Analyzer

Dynamic Tensiometers calculate the change in liquid surface tension over time by measuring bubble pressure or droplet shape variation. They are used to monitor processes such as the wettability of coatings, the spreading speed of inks, and the stability of printed ink layers, as well as to control the effectiveness of surfactants in paper sizing and plastic coating.
