Brief description：The contact angle refers to the angle formed at the three-phase contact point of solid, liquid, and gas on the surface of a solid when a drop of liquid is placed on a horizontal solid surface, with the tangent lines of the gas-liquid interface and the solid-liquid interface enclosing the liquid. A contact angle tester is mainly used to measure the contact angle of a liquid on a solid, which shows the wettability of the liquid on the solid. It can measure the contact angles of various liquids on different materials.
Industry Applications：Water/oil contact angle test, solid surface energy measurement.
