The surface tension is an important process and quality parameter in the industry. You can find the surface tension in a wide range of applications, such as coating, painting, electroplating, gluing, cleaning and in many other chemical processes. SITA tensiometers measure the dynamic surface tension of liquids according to the bubble pressure method. This enables their use in both, research and development laboratories, as well as process monitoring directly at the plant.

The SITA tensiometers are characterized by high precision measurements and an intuitive operation.
