Full-automatic Contact Angle Goniometer for Liquid on a Solid

It is used to determine the wetting properties of liquid to solid, through measuring the contact angle to calculate, measure the adhesive force, tension force etc. it’s widely used in petroleum, chemical, medicine, paper making, dye industry as well as science research hand academy education.

Accord with national standard

1.GB/T 24368-2009(detection of hydrophobic pollutants on glass surface);

2.SY/ t5153-2007 (reservoir rock wettability measurement method);

ASTM D 724-99 (2003) (test method for wettability of paper surfaces);

4.ASTM d5946-2004 (measurement of the contact Angle between plastic film and water);

5.ISO15989 (measurement of water contact Angle of plastic film and thin plate corona treated film);

Features:

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.
