Contact Angle Metering System - ACAM D1

The contact angle is one of the most common ways of measuring the wettability of a surface. Wettability refers to how a liquid is deposited on a solid surface spreads out. It is determined by measuring the angle created when a liquid comes into contact with a solid surface.


  • For the Analysis of the Wettability of a Surface
  • For Checking the Homogeneity of a Surface during the Preparation of Nano / Micro-level Homogeneous Thin Film by Spin & Dip Coating Technique
  • For the Preparation of Various Detergents, Fabric Colours, Inks, Anti-reflective Coatings
  • Widely used in the Textile, Printing, Detergent, Coating & Optical Industries
