Face Mask Air Exchange Pressure Difference Tester
Face Mask Air Exchange Pressure Difference Tester also called mask breathility tester is to determine the breathability of medical face mask materials. The tester can measure the differential pressure (Delta P) required to draw air through a measured surface area at a constant air flow rate is used to measure the air exchange pressure of the medical face mask materials. By providing the suction air through the holding sample, the tester can measure the Delta P by differential pressure transducer. It is to determine the air permeability and using comfort of the materials for medical mask.
Features:
1. Adopt suction air source as the power source of the instrument, not limited by the space of the test site;
2. Equipped with a precision differential pressure sensor, which digitally displays the pressure difference on both sides of the sample;
3. The special sample holder ensures that the sample is firmly held.
Face Mask Air Exchange Pressure Difference Tester Test Standards:
YY 0469-2011:Surgical mask
YY 0969-2013:Single-use medical face mask
EN 14683:2014:Medical face masks - Requirements and test methods
Working principle:
Set the output of the air flow through the gas flowmeter, make the air flow pass through a certain area of test sample, detect the current pressure through the pressure sensor and calculate the pressure difference.
