The portable contact angle meter PCA-11 is a compact and lightweight device for fully automated on-site measurements of contact angle, surface tension, and surface free energy of solids.
Testing on-site for quality control and surface wettability evaluation, characterized by the contact angle, is often required during manufacturing processes or in the field. The PCA-11 can be used on any material such as glass, metal, film, paper & pulp, polymer, wood, etc., that must be measured on-site or that, due to their size or shape, cannot be analyzed with the usual stationary contact angle measuring instruments.
Weighing only 650g, combined with the single-click fully automated operation and precise measurements, the PCA-11 is the ideal solution for non-destructive surface evaluations.
