Respiratory Resistance Tester Test principle:

By simulating the exhalation of the human body and the airflow generated by inhalation, the exhalation resistance and inhalation resistance generated when wearing the mask are detected, so as to determine whether the person wearing a mask with a certain filtering efficiency affects the normal breathing of the human body purpose.


Expiratory resistance, inspiratory resistance indicators:

Exhalation resistance, inhalation resistance index function Exhalation resistance and inhalation resistance are one of the important indicators that represent whether the human body will have respiratory discomfort when wearing a mask. If the resistance is too large, it will affect the normal breathing of the human body, and the more unsuitable for wearing, the masks with exhalation resistance greater than 250Pa and inhalation resistance greater than 350Pa are all unqualified products.
