About Sigma 703D Force Tensiometer

UK based Dyne Testing offer the Sigma 703D Force Tensiometer, a simple standalone and robust digital force tensiometer for accurate measurement of surface and interfacial tension. Manual critical micelle concentration (CMC) measurements can also be conducted.

The Sigma 703D is extremely easy to use.  With convenient control keyboard operations and open design there is no need for an external computer.  Measurements are displayed in real-time on the large digital screen integrated into the instrument and can be transferred to a computer using the Data receiver software.

For quick and reliable stand-alone operation and manual control, Sigma 703D is a great choice. The major difference between the Sigma 703D and Sigma 702 models is the manual sample stage of Sigma 703D.
