LCD screen contact angle measuring instrumentUsed to test the contact angle between liquid and solid, that is, to determine the wettability of liquid to solid by measuring the size of the contact angle formed between liquid and solid. Widely used in the testing and research of silicon crystals, liquid crystals, glass, fibers, synthetic materials, inks, coatings, pesticides and other fields.

The LCD screen contact angle measuring instrument has multiple measurement functions:

1. Measurement of static and dynamic contact angles: The static contact angle is the contact angle of a liquid droplet after it stabilizes on a solid surface, while the dynamic contact angle is the contact angle of the liquid droplet during its change on the solid surface.

2. Measuring the surface free energy of solids and interfacial tension of liquids: By measuring the contact angle, the surface free energy of solids and interfacial tension of liquids can be indirectly calculated.

3. Measuring the forward backward angle and rolling sliding angle: These parameters help to understand the flow and wetting behavior of liquids on solid surfaces.

　　LCD screen contact angle measuring instrumentIt can automatically identify and adjust the imaging resolution to ensure the accuracy of measurement results. It can automatically find the baseline between the droplet and the solid surface, and fit the contour of the droplet to accurately measure the contact angle. This device can gain a deep understanding of the interaction between liquid and solid surfaces by accurately measuring parameters such as contact angle, providing strong support for scientific research and production.
