Theta Theta is the advanced and versatile optical tensiometer for highly accurate measurements of contact angle, surface tension and interfacial tension. Theta can measure static and dynamic contact angles, static and semi-dynamic surface/interfacial tension, surface free energy and drop. The available drop profiles are: sessile drop, pendant drop, receding contact angle, tilting drop, advancing contact angle, captive bubble, meniscus and reverse pendant drop.Theta harness the power of full automation to deliver best-in-class performance for R&D, quality control and process control.Theta captures drop images and automatically analyzes the drop shape as a function of time. The quality of measurement thus depends on the quality of pictures and the analysis software. |
