Medical face mask differential pressure 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.wGeTextile Testing Instruments, Testing Equipment Manufacturer
