YYS Mask Gas Exchange Pressure Difference Tester
The product complies with YY0469-2004 "Technical Requirements for Medical Surgical Masks" and YY 0969-2013 "Disposable Medical Masks"

According to the standard requirements, the gas exchange pressure difference detector for medical masks determines the breathability performance of the mask by measuring the pressure difference between the gas exchange on both sides of the mask (i.e. the damping of the mask to the airflow), and the instrument test results are accurate.YYS Mask Gas Exchange Pressure Difference Tester
