Research on Verification Device for Air Permeability Standard Used in Tobacco Industry

The air permeability standard for tobacco is the main instrument used in measuring paper air permeability. The accuracy of its measurements is critical for determining the transmittance of harmful gases in flue gas, which in turn has significant implications for human health. This paper explores and investigates a verification device for the air permeability standard in accordance with current National Standards. We designed a specialized fixture and constructed a complete apparatus that meets the necessary requirements. With this device, air permeability standards can be effectively traced and measurements in the region can be made accurately and reliably. By reducing the amount of tar and other harmful substances in cigarettes, this research contributes to the protection of human life and health.
