1、 Overview: The FBT-5 fully automatic specific surface area meter is mainly made according to the relevant provisions of the national standard GB/T8074-2008 "Method for Determining Specific Surface Area of Cement" and improved with reference to the American ASTM C204-75 permeability method. The basic principle is to use a certain amount of air to measure the resistance experienced by a compacted powder layer with a certain porosity and thickness. It is mainly used to determine the specific surface area of cement, and can also be used to determine the specific surface area of powdered materials such as ceramics, abrasives, metals, coal, food, gunpowder, etc
