add-on module for measurements of roll-off speed and roll-off acceleration

  • DMo-series-1
  • DMo-series-2
  • DMo-series-3
  • DMo-series-4
  • DMo-series-5
The three models of the DMo-WA-series are specially designed contact angle meters for measurements of disk-shaped substrates such as wafers with a diameter of up to 12inches.
All models feature a 305mm diameter rotation table and a computer controlled dispenser which allow for automatic measurements of contact angle, advancing and receding angles, as well as analysis of surface free energy of solids.
Optional, a tilting stage for the measurement of roll-off angles is also available.
