　　The water drop angle tester mainly tests the contact performance of solid, liquid and gas interfaces.

　　The water drop angle is defined as the angle between the gas-liquid interface and the solid-liquid interface at the three-phase interface of solid, liquid, and gas. The water drop angle is a measure of the humidity of the solid surface, and most of the solids are used. For the measurement, a low contact angle means that the surface with high humidity (hydrophilic) is easy to stick. A high contact angle of water droplets indicates that the surface shows hydrophobicity, and the surface has heavy 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 a measure of the humidity of the solid surface. The measurement is performed using most of the anchor droplets. A low contact angle indicates high humidity (hydrophilicity, hydrophobicity) and low surface energy.
 

　　Product Features
 

　　The water drop angle tester is manufactured with modern technology. The instrument uses an advanced dedicated CMOS digital camera, equipped with a high-resolution zoom microscope and a high-brightness LED background light source system. It is equipped with a three-dimensional sample stage and can be used for up and down, left and right, front and rear directions of the workbench. move. Realize micro-injection and precise movement up and down, left and right. At the same time, a workbench with a telescopic rod structure is also designed, which can adapt to the occasions where the thickness of different users is increased. The instrument frame can be adjusted appropriately according to the size of the style, which expands the scope of use of the instrument. The software is equipped with a correction function, and the results after multiple tests can be saved in the same report at the same time, allowing users to better control the material data. The instrument is beautiful in design, simple in operation, and meets the needs of users. It is suitable for users who measure contact angle in various industries.
