Medical Face Mask Air Exchange Pressure Difference Tester

Medical Face Mask Air Exchange Pressure Difference Tester is used to determine the breath ability of Protective face masks.

The test principle is, measuring the differential pressure required to draw air through a measured surface area at a constant air flow rate, or to test the air exchange pressure of the medical face mask material, which indicates the breath ability of medical face masks.
