1. Summary

The automatic contact angle tester refers to the tangent line of the gas-liquid interface taken at the intersection of gas, liquid, and solid phases. The angle θ between this tangent line and the solid-liquid boundary line on the liquid side is the main method for measuring surface properties today.

(Some testing functions require the purchase of specialized accessories to complete)
1. The wetting behavior of liquids on solid surfaces, such as spreading, permeation, and absorption, is measured by the droplet method to determine the static contact angle;
2. Measurement of the advance angle, retreat angle, contact angle hysteresis, rolling angle, and dynamic contact angle of materials on solid surfaces;
3. Continuous real-time research and process recording of absorbing materials, analysis of contact angle variation curve over time;
4. Contact angle measurement of various special materials, such as powders, curved surfaces, superhydrophobic/superhydrophilic samples;
5. Contact angle test of materials immersed in liquid using the attachment drop method;
6. The suspended droplet method is used to measure the interfacial tension, polarity, and dispersion components of various liquids;
7. Calculate the surface free energy of solids and analyze their polar dispersion components;
8. Analyze the adhesion energy of liquids on solid surfaces, evaluate the uniformity and cleanliness of solid surfaces, etc.
