Contact Angle Goniometer

Measurement of static contact angle, dynamic contact angle (advancing and receding contact angle) and roll-off angle of specific liquids on coatings or other surfaces. Contact angle can give you information about the wettability of surfaces, detect changes in surface properties induced by the environment, and measure surface- and interfacial tension of liquids. Water, surfactant solutions or low viscosity organic compounds can be used to measure. Sample temperature can be set between -30 and 400 °C and humidity of surrounding air can also be regulated. Measurement of air or immiscible liquids in water is possible. Humidity chamber can be used separately from the CA equipment.
