Mask gas exchange pressure difference measuring instrument
Overview
The mask gas exchange pressure difference tester (gas exchange pressure difference tester) is based on the test principle of the standard YY0469-2011 "Technical Requirements for Medical Surgical Masks", which uses a differential pressure sensor to achieve the pressure difference detection between the internal pressure and the external pressure of the placed mask. It is equipped with special tooling devices to achieve the test sealing performance of the product. It is mainly used for measuring the gas exchange pressure difference of medical surgical masks / mask fabrics, and can also be used to measure the gas exchange pressure difference of other textile materials.
Applicable standards
· YY0469-2011 Medical surgical mask
· YY0969-2013 Disposable Medical Masks
· EN14683-2014 Medical face masks-Requirements and test methods
