Medical Face Masks Breathability Tester is used to measure the breathability of the medical face masks.

Install the mask on the channel (clamp) with fixed cross-sectional area, start the vacuum pump, the airflow with specific flow rate will generate 

a certain air flow through the test sample, so as to calculate the permeability (differential pressure) of the mask.

RF4308AP Tester, built-in precision air pump, flow sensor, differential pressure sensor, single chip microcomputer control, precise control of 

flow rate and differential pressure measurement.
