Envelope Surface Area Analyzer
PMI’s Envelope Surface Area Analyzer (ESA) provides a simple, fast, and reliable method for measuring external surface area — a measurement not readily achieved using static nitrogen adsorption (BET) methods. The ESA utilizes flow permeameter combined with a sophisticated self-adjusting viscous-flow controller, enabling accurate testing of a wide range of powders and other materials, including samples with surface areas of only a few square meters per gram.
