Product details:

This instrument is mainly made in accordance with the relevant provisions of the national
standard GB8074–87 Determination method of cement specific surface area-Bureau’s method, and with reference to the AmericanASMTC204–75 air permeability improvement.
The basic principle is to use a certain amount of air to measure the resistance when passing through a compacted powder layer with a certain porosity and a certain thickness. It is widely used in the determination of cement, ceramics, abrasives, metals, coal, food. , the specific surface area of ​​powder materials such as gunpowder.
