ASR-5634 Contact Angle Tester Water Drop Angle Measuring Instrument
The automatic water drop angle tester (water drop angle) refers to a drop of liquid on a solid horizontal plane, at the solid-liquid-gas three-phase junction point on the solid, and its gas-liquid interface and solid-liquid interface are two tangent lines. The angle formed by the liquid phase sandwiched therein. When the droplet is freely in a space that is not affected by the force field, it is spherical due to the presence of interfacial tension. However, when a droplet is in contact with a solid plane, its final shape depends on the cohesive force inside the droplet and the relative magnitude of the adhesion between the droplet and the solid. When a droplet is placed on a solid plane, the droplet can be automatically spread over the solid or present as a droplet of the fully automatic water drop angle tester with the solid.
