Contact angle measuring instrument principle and components-Sindin Precision

2022-03-30

How a contact angle measuring instrument works:

The syringe needle drops a drop of the liquid to be measured on the substrate, the drop will adhere to the surface of the substrate and cast a shadow, and the projection screen uses optical magnification to project the image onto the screen for measurement; through the principle of optical projection imaging, the Fidelity acquisition and precise analysis of gas, liquid and solid three-phase interface profiles.


Contact angle measuring instrument components:

The contact angle measuring instrument consists of a video acquisition system, an injection system, a control system, a three-axis moving sample platform and analysis software, as shown in the figure below.
