See System PDF Tisk

See System E is a portable computer-based instrument for contact angle measurement and surface energy determination.It can be also used for ISO 27448:2009 determination of the self-cleaning performance of photocatalytic materials such as that containing titanium dioxide.


See System E

Main features

  • Portable instrument of small size connected through USB 2.0 port.
  • Rugged aluminium body.
  • Colour 2Mpix (1600 x 1200) UVC camera with high-resolution glass objective lens.
  • Table for samples up to 10 x 10 cm, movable horizontally in  2D.
  • No special light source is needed, only a daylight, no problem with drop evaporation.
  • Periodical image capturing for time-dependent studies (e.g. of wettable samples).
  • TÜV declaration of conformity: English, Czech.

Supported surface-energy models 

  • The software enables the calculation of the surface energy on the basis of the most often used models: Owens-Wendt-Rable-Kaeble, Lifshitz-van der Waals/acid-base, Li-Neumann, Kwok-Neumann, Wu Equation of State,  Zisman.
  • Regression variants of Owens-Wendt & acid-base models are also supported.


The prices include the instrument and software for contact angle and surface energy measurement. Software for self-cleaning performance is sold separately.

Contact angle diagnostics can be used for various purposes. Two different software packages are available:

  • See System for Surface Energy Measurement - for contact angle measurement and caculation of surface free energy of solids on the basis of commonly used models as Owens-Wendt-Rable-Kaeble, Acid-Base, Zisman, Wu, Neumann, ...
  • See System for Self-Cleaning Measurement - for calculation of self-cleaning performance on the basis of contact angle measurement according to ISO 27448:2009 test method.
