PMIs 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 ESAs 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.XjzTextile Testing Instruments, Testing Equipment Manufacturer

Application>XjzTextile Testing Instruments, Testing Equipment Manufacturer
Providing the user with a surface area measurement in less than five minutes, the main application of the ESA is quality control. Samples tested include pharmaceutical powders, electrode components, ceramic powders, fibrous materials, and other porous substances. The ESA is utilized for this function in several industries, such as: Battery Separator Ceramic Chemical Pharmaceutical Powder Metallurgy.XjzTextile Testing Instruments, Testing Equipment Manufacturer
