OCA – Optical contact angle measuring and contour analysis systems

Part Number: OCA

The OCA Series by DataPhysics comprises high-precision optical contact angle goniometers and drop-shape analyzers. These instruments determine surface and interfacial properties—such as static/dynamic contact angles, surface energy, interfacial tension, and work of adhesion—through advanced imaging and dosing technologies. With modular designs that support lab-scale research or field applications, the OCA lineup offers reliable performance across industries like materials science, coatings, bioengineering, and quality control
