DROPimage
CA
DROPimage
CA is our entry-level software solution. This program ships standard
with our
Model 190 CA Goniometer and can be
later upgraded to DROPimage Pro or Advanced if your requirements
become more demanding. The two primary tools in DROPimage CA are the Contact
Angle Tool and the Calibration Command as outlined below. Additional
menus are available for: options, saving and opening images, data
export, video setup, zooming, and baseline setup. DROPimage CA uses the
same algorithms, video control, and methodology employed in the more
advanced versions of DROPimage, but lacks the surface energy and surface
tension tools.

Contact
Angle Tool |
|
The
Contact Angle Tool characterizes the behavior of a liquid on a
solid. When a small volume of liquid is placed in contact with a
solid surface, a sessile drop forms.
When equilibrium is established, there is a liquid-solid interface
between the two phases. The tangent angle between solid and liquid
is known as the contact angle. DROPimage CA is well suited for
testing on hydrophilic as well as hydrophobic materials. |

Calibration
Command |
|
When
the instrument is shipped, the system is fully calibrated. However,
it is recommended that the instrument be calibrated after
installation. The Calibration command uses a ball with a precise
diameter to calibrate the magnification of the camera, resulting in
100% accurate readings. All ramé-hart systems ship
with a proprietary calibration tool so calibration can easily be
performed by the customer at any time. |
