PCA 200: Portable Contact Angle Goniometer for On-Site Surface Energy Analysis


Streamline production and quality control with the PCA 200, a portable contact angle device for on-site surface energy measurement. The DataPhysics PCA 200 is a portable contact angle goniometer designed for unmatched versatility and precision in surface characterization. This compact instrument empowers you to perform reliable contact angle measurements on-site, directly on your solid samples, regardless of size or location.

Key features for enhanced efficiency:
  • Mobile and Stand-alone: The compact, handheld design allows for on-site analysis, wherever your samples reside. The integrated computer and software eliminate the need for a separate PC, making it a truly wireless, stand-alone measurement solution.
  • Live Preview Display: Ensure accurate measurements every time with the live preview image displayed on the device. Inspect and adjust the target area before measurement, and view the results instantly afterwards.
  • Double the Efficiency: The PCA 200 dispenses two test liquids (diiodomethane and water) simultaneously, measuring their contact angles and calculating surface energy in a single step. This significantly improves workflow efficiency.
  • Fast and Reliable Surface Energy Determination: Leveraging established interaction models (OWRK and Wu), the PCA 200 delivers rapid and reliable surface energy readings. These models provide a differentiated analysis of the polar and dispersive components of the surface energy.
  • Long Operating Time: The powerful lithium-ion battery ensures extended operation, while the large test liquid cartridges minimize refill interruptions, allowing you to complete numerous measurements without downtime.

The PCA 200 is the ideal tool for production and quality control professionals who require fast, accurate surface energy analysis directly on-site.
