The definition of water drop angle is the angle between the gas-liquid interface and the solid-liquid interface at the intersection of solid, liquid and gas. The water drop angle is the scale to show the humidity of solid surface, which is measured by most of the solid droplets. The low contact angle indicates that the surface with high humidity (hydrophilicity) is easy to paste. High contact water drop angle indicates that the surface shows hydrophobicity, heavy surface organic pollution or poor surface adhesion. The contact angle of the liquid in contact with the flat solid surface is measured by the end point of the water drop curve in the liquid solid gas junction and the contact point of the solid surface to analyze the surface cleanliness. The contact angle is the scale to display the solid surface humidity, which is measured by most of the fixed object drops. The low contact angle indicates the high humidity (hydrophilicity, hydrophobicity) and the low surface energy.

The instrument is manufactured by modern technology. It adopts advanced special CMOS digital camera, high-resolution zoom microscope, high brightness LED background light source system, and three-dimensional sample table. It can move up and down, left and right, front and back. To achieve micro injection and up and down, left and right precision movement. At the same time, the working table with the structure of the expansion bar is designed, which can adapt to the situation of increasing the thickness of the materials of different users. The frame of the instrument can be adjusted appropriately according to the size of the pattern, which enlarges the scope of use of the instrument. The software is equipped with correction function, and the results after multiple tests can be saved in the same report at the same time, so that users can better control the material data. The design of the instrument is beautiful, easy to operate and meet the needs of users. It is suitable for the users of measuring contact angle in various industries.
