Sigma 702/702ET

Sigma 702 and Sigma 702ET are standalone tensiometers offering high resolution and precision for surface and interfacial tension measurements, as well as non-automatic CMC determination.


Applications

Sigma 702 and 702ET are force tensiometers for determination of:

  • Surface tension
  • Interfacial tension
  • Critical micelle concentration
  • Absorption  
  • Density

 

Measuring with Sigma 702/702ET


Results are displayed on a large integrated digital screen. Open design and convenient control keyboard operations make Sigma 702 and 702ET extremely easy to use instruments. Sigma 702 enables precise temperature control thanks to an integrated water-jacket vessel holder, mounted on a motorized sample stage. Sigma 702ET is also equipped with a motorized sample satge, but without water jacket vessel order. Sigma 702ET is specifically designed for oil-water interfacial tension measurements in line with ASTM and IEC standards. A software designed for oil-water measurements is provided with the Sigma 702ET. Sigma 702ET can also be connected to an external PC for additional data storage and simple reporting. The data collection software is provided with the instrument.
