Contact Angle Meter


Product Overview

  • Easy "half angle" determination
  • Operator independent consistent measurements
  • Dyne level readings from 10 to 70
  • Simple finite liquid dispensing that employs delicate liquid placement (sessile drop)
  • Bright, clear image on a large screen for display
  • A remote light source keeps heat away from the sample
  • Platform configurations for small samples, films, printed circuit boards (PCB), plastic ball grip array (PBGAs), round samples (spherical and tubular)
  • Standard input voltage - 120 VAC (60 Hz)

What is Surface Energy?

  • Surface energy is most evident in how a surface interacts with an applied liquid. Like color and texture, surface energy is a physical property. When paint is applied to a sheet of glass, it will typically "ball up" because it does not stick well to the surface. This is surface energy in action. Conversely, when liquid is applied to a different material and disperses, this is also surface energy.

Patented Measurement Method

  • The CAM-Plus contact angle meter provides a patented method ("half angle") for quantifying surface energy relative to other measurements on other surfaces. This information makes it possible for accurate prediction of a surface reaction to coatings, eliminating costly trial-and-error methods. CAM-Plus is designed for test methods ASTM D20.19, D724, D5946 and TAPPI T458 cm-94.
