DCAT 9 Tensiometers

​The DCAT 9 Tensiometers is a fully automated tensiometer developed by DataPhysics Instruments, designed for precise, weight-based measurements of surface and interfacial tension, as well as the density of liquids and solids. As a powerful entry-level model in the DCAT series, it offers a comprehensive solution for researchers and professionals in surface science, materials testing, and quality control.
