Overview

This series is a customized sample table with a large contact angle measuring instrument based on the size of the user's sample. By testing the size of the contact angle formed by the liquid on the solid surface, the wettability of the liquid on the solid can be determined, and then the cleanliness and treatment process effect of the solid surface can be tested. Widely used for pollution detection, adhesive ability analysis, and surface treatment process evaluation of large sample surfaces such as glass, LCD screens, touch screens, and packaging substrates.
