Gas Exchange Pressure Difference Testing Machine For Medical Facial Mask 220V Yy0469-2011 Standard

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.

3. Meeting Standards:
