Contact angle measuring instrument It is mainly used to measure the contact angle of liquid to solid, that is, the wettability of liquid to solid. This instrument can measure the contact angle of various liquids to various materials. This instrument plays a very important role in scientific research and production of petroleum, printing and dyeing, medicine, spraying, mineral processing and other industries.
 
Contact angle tester Principle:
 
When the droplet is free in the space not affected by the force field, it is spherical due to the existence of interfacial tension. However, when the droplet contacts the solid plane, its final shape depends on the cohesion inside the droplet and the relative size of the adhesion between the droplet and the solid. When a droplet is placed on a solid plane, it can automatically spread on the solid surface, or exist as a droplet with a certain contact angle with the solid surface.
