The instrument has a 32-bit Microsoft Windows95 based software, which allows analysis of contact angles, critical surface tension (Zisman plot) and surface free energy of solids (Fowkes, etc.). Determination of contact angle and surface tension is based on true Young and Laplace equation.

Instead of using separate files for each measurement the software contains an internal database system where all the recorded data is stored. This allows a convenient method to keep all the data organized for future analysis. To save space recordings are saved using our proprietary image compression which retains all important information. There are separate databases for liquids and solids where all information about the test materials is be stored.

Specfications:

Contact angle measuring range:	0...180 degrees.
Inaccuracy:	+/- 0.5 degrees
Calculation method:	Curve fitting based on Young & Laplace equation, completely automatic calculation. Calculates separate contact angle for either side and then the mean value. For reduced calculation time circular and polynomial fits are also available for contact angle calculations.
Maximum sample size:	unlimitedx150x50mm (lxwxh)
Frame interval:	Fast mode: 40...1000 ms, the number of images depends on the amount of the computer memory. Normal mode: 1...1000 seconds, unlimited number of images.
Camera:	CCD-camera with telecentric zoom optics.
Lightning:	LED based background lightning. Built in stroboscope allows short exposure times and full 512 X 512 resolution.
Dispenser:	Manual (computer controlled as an option)
Computer requirements:	Pentium, SVGA graphics, Windows95/98 or NT operating system.
