The cement specific surface area tester is an improved detection device based on the American ASTM204-80 air permeability method. It is mainly used to measure the specific surface area of non-porous powder materials such as cement, ceramics, and metal powders. This instrument calculates the resistance change of air penetrating a powder layer with a specific porosity, in compliance with national standards such as GB8074-87/2008, and is widely used in industrial laboratories
