Contact Angle and Surface Tension Measurement Device

Product Introduction:

The angle formed between the tangent line drawn from the three-phase contact point and the contact line of the liquid and the surface is called the contact angle. This angle provides a measure of surface wettability. In general, there are two types of contact angle: static contact angle and dynamic contact angle.

The dynamic contact angle includes forward, backward, hysteresis and rolling contact angles. A contact angle measuring device consists of an illumination and imaging system and is designed to store an image of the droplet profile on a solid surface. In older systems, a microscope was used instead of a camera, and the images were analyzed by the operator. In the new systems, a high-speed camera with a suitable resolution and automatic image analysis software are used. To measure the contact angle, there are many methods, including static and dynamic Sessile Drop methods. By using the contact angle measuring device, in addition to evaluating the wettability level, it is possible to ensure the quality of the surface properties of the coatings.
