SensaDyne Instrument Division  manufactures the world's most advanced computer-based instruments for intermittent and continuous measurement of dynamic and equilibrium (static) fluid surface tension. The company was formed and incorporated in 1981 in Madison, Wisconsin, by Victor P. Janule. The current President is Herb V. Daniel.

SensaDyne has developed, patented, and commercialized a number of fluid surface tension measurement instruments, for both laboratory and in-process applications, based on the maximum differential bubble pressure method. This method evolved from research done in cooperation with the University of Wisconsin, Department of Chemical Engineering. In July 1982, SensaDyne relocated to Milwaukee, Wisconsin, and then in 1992 to new and expanded facilities in Arizona.

SensaDyne markets its instruments throughout the world, either directly from its sales office in Arizona, or through a network of domestic and worldwide representatives. Technical support is available by contacting its Arizona office at sensadyn@ix.netcom.com.
