Next-Generation Tensiometry

PAT-2S Stand-Alone Tensiometer

The PAT2S is the latest version of PAT instruments and continues the great tradition of PAT1M. The most striking improvements in the newly designed stand-alone tensiometer PAT2S are the higher resolution of the video camera and the more flexible mechanical construction which allows to better adapt the instrument to the requirements of the user. In addition to the higher resolution also high speed cameras with high frame rates is embedded in the corresponding software.
