Envelope Surface Area Analyzer
Description:
TECH INC.’s Envelope Surface Area Analyzer (ESA) offers a simple, fast, and reliable technique for external surface area measurement – a measurement not readily achieved by static nitrogen adsorption (BET) methods. The ESA’s innovative use of flow permeametry combined with its sophisticated self-adjusting viscous-flow controller enables testing of a wide range of powders and other samples, including materials with surface areas of only several square meters per gram.
