Overview

This machine adopts a lightweight and portable design, which can be directly placed on the surface of the test sample to test the size of the contact angle formed by the liquid droplets on its surface, thereby detecting the cleanliness, adhesion ability, and treatment process effect of the surface. Widely used in non-destructive and mobile testing of larger samples (such as glass, liquid crystal screens), irregular samples (such as car bodies, bathtubs), special working environments (such as outdoor environments, assembly lines), and other fields.
