1. Products description:
Mask Gas Exchange Pressure Difference Testing Machine is based on the test principle of the standard YY0469-2011
"Technical Requirements for Medical Surgical Masks". The
differential pressure sensor is used to achieve the pressure
difference between the internal pressure and the external pressure
of the mask. The test item is equipped with a special tooling
device to achieve the test tightness of the product. It is mainly
applicable to the measurement of the gas exchange pressure difference of medical
surgical masks / mask woven fabrics. It can also be used to determine the gas exchange pressure
difference of other textile materials.
2. Application:
--- Determination of gas exchange pressure difference between
surgical masks/woven masks.
--- Determination of gas exchange pressure differences of other
textile materials.
