CONTACT ANGLE
METER:
Dyne Technology offers the
CAM
PLUS,
contact angle meter for surface energy testing of films or solid substrates.
A rugged, simple-to-use, highly repeatable QC and analytical tool for measuring
the contact angle on a variety of substrates.
Contact Angle Measurement is the preferred and most accurate method of much
vital laboratory measurement and research for determining the interactions at
the solid/gas/liquid interface. The Contact Angle Meter is an ideal industrial
or academic tool for product development engineers, R & D engineers who need
precision and repeatability. Contact Angle Measurement combines high technology
test instrumentation and a non-destructive testing method to allow an accurate,
objective and repeatable analysis to be made. Using the CAM PLUS contact angle
meter you can compare the effects of a range of surface treatments and gather
data that correlates to various surface conditions e.g. lubricity, wettability,
surface energy etc.
What is Contact Angle?
The contact angle is the angle at which the liquid/solid/air interface meets the
solid surface. When a liquid droplet is set onto a smooth homogeneous horizontal
surface, it may spread out over substrate and the contact angle will approach
zero if complete wetting takes place. Conversely, if wetting is partial, the
resulting contact angle reaches equilibrium in the range of the material’s
surface energy. The smaller the contact angle the greater the wettability or
surface energy of the substrate is said to be. Contact angle is a good measure
of surface wettability.
Various methods of measuring surface wettability are available from Dyne
Technology: Contact Angle Measurement,
Dyne Test Pens,
Dyne Test inks/fluids
etc.
Half-Angle Technique-Repeatability in Measurements.
By drawing a line from the liquid/solid/air interface point and the apex of a
droplet of distilled water the contact angle can be more accurately and
precisely identified. This “half angle” measurement technique eliminates
potential sources of human error in finding the tangent line.
Projection Technique - Simplifies
Discussion of Results.
By projecting the image of the droplet as it sits on top of the
substrate, several engineers, students, researchers or QC personnel can
simultaneously see and discuss the results of the work. With the Cam Plus
contact angle meter the droplet image is magnified and displayed right-side-up
for simpler measurements.
The “Dyne” CAM PLUS series Contact Angle Meter is available in 3 models:
