Angle de contact – Mesureurs

GENEQ > Essais sur Matériaux > Angle de contact – Mesureurs

The CAM-PLUS series of contact angle meters are rugged, simple-to-use highly repeatable QC and analytical tools for measuring the contact angle on a variety of subtrates

Using the patented projection screen HALF-ANGLE™ measuring technique, the CAM-PLUS series of contact angle meters bring simplicity of measuring to the QC, R&D or process areas. They bring highly repeatable contact angle measurements, as well as, detailed surface energy analysis to users in a simple-to-use fully-integrated package. They can be used for evaluation of solid surfaces for adhesion, determining the hydrophobic and hydrophilic nature of the substrate, surface cleanliness or liquid absorption rates.

HALF-ANGLE TECHNIQUE

Repeatability in Measurement

By drawing a line through the Apex of the drolet from the interface point between the liquid/solid surfaces, the contact angle can be more absolute and repeatable as compared to tangent line approaches. This eliminates potential sources of human error in measurement of 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 students, researchers or QC personnel can simultaneously discuss the results of the work. The droplet image is magnified and displayed right-side-up for simpler measurements.

FEATURES FOR FAST, SIMPLE MEASURING

Tantec's unique rail loading system allows you to quickly and easily load samples and push them into the "measuring" position. This facilitates easy sample loading, separated from the measuring location. The syringe can be easily loaded by loosening its hold-down thumbscrew, sliding out the micrometer syringe assemblly and charging it with the test liquid.

OTHER ADVANCES

Several other features make the CAM-PLUS series a "plus" to work with. The newly developed fiber optic light source increases the light intensity for easier measuring in brightly-lit rooms and defines the image more crisply.The micrometer syringe assembly assures measured droplets can be formed time and time again.
