The
OCAH 200 is a High-speed contact angle measuring device for the determination
of fast sorption and spreading with up to 360 images per second. Particularly
to measure fast adsorption and absorption processes on paper, textiles,
membranes, filter cloth and porous solids.
For the software-controlled measurement and analysis of
- Static
and dynamic contact angle according to the Sessile and Captive Drop
method
- Analysis
of the drop shape according to the Pendant Drop method
-
Wetting behavior on solid surfaces
- Surface
free energy of solids and their components
- Surface
and interfacial tension out of the analysis of the drop shape
The
OCAH 200 consists of the basic instrument with the following technical
equipment:
- Dosing
bay for installation of the optional manual syringe units and single
or multiple (max. 4) needle support with a vertical and horizontal
fine adjustment
- Measuring
stage, adjustable in three axis for accurate sample positioning
- Lens
mount with adjustable tilt
- High-performance
six-fold power zoom lens with an integrated continuous fine focus
- High-speed
video system with adapter and CCD-camera
- High-performance
video digitizing board (frame grabber) for the PC
- Halogen
lighting with continuously adjustable intensity without hystereses
for a homogeneous back lighting
- Control
and measuring electronics with built-in digital temperature display
and serial RS 232C interface
- Power
supply with automatic voltage adjustment
