Face Mask Breathability Tester

The 'PRC' Breathability Tester is based on the principle of differential pressure. It is used to determine the face mask's resistance to airflow. In breathability test, A controlled flow of air is given through the mask, and the pressure is measured before and after the test.The difference in pressure is divided by the surface in cmH2O of the sample. A lower breathing resistance indicates a better comfort level of the user and the higher level of breathing indicates a less comfort level of the user.
