Components for the top view distance method


Module for measuring contact angle using the top view distance method

  • Bookmark

The TVA100 module equips your instrument for carrying out surface analyses using the top view distance method. The measuring head’s precision dosing feature produces a drop with defined volume. Two diodes with an accurately adjusted spacing illuminate the drop from above. A camera monitors the reflected light points, the spacing of which correlates to the contact angle. By measuring from above, surfaces in depres­sions or concave samples can be analyzed. Instruments with this patented measuring method can be obtained only from us.


The easy fitting of the module enables a rapid changeover between top view distance measurement and conventional contact angle measurement from the side.

The following are included in the scope of supply:


  • Precision dosing unit for producing accurate drop volumes
  • High-quality optical components and high-resolution camera
  • Pre-prepared measuring procedures in the software for rapid results
