The key to micro measurement: analysis of high-precision fully automatic contact angle measuring instrument

The fully automatic contact angle measuring instrument is an instrument used to measure the contact angle between liquid and solid materials. It is mainly used to characterize the wetting performance of liquid on the surface of solid materials. The image of the droplet is obtained through optical imaging, and the contour of the droplet image is fitted with a mathematical model using computer software to obtain the contact angle or surface tension. Surface energy calculation and wetting analysis are also performed.
