Differential Pressure Tester
The output of the airflow is set by the gas flowmeter to make the airflow pass through a certain area of the test sample. The current pressure is detected by the pressure sensor and the pressure difference is calculated.

BR-800 Mask Differential Pressure Tester
Product introduction
The respiratory resistance tester is suitable for measuring the inspiratory resistance and expiratory resistance of respirator and respirator protective devices under the specified conditions, and is used for the relevant inspection and inspection of the general respirator products by the manufacturers of the national labor protection agency. The instrument is composed of air source which can adjust the flow, human head model regulated by the standard, two sets of pipeline systems of inspiratory and expiratory, respiratory resistance measurement system, etc. It conforms to YY 0469-2011 medical surgical mask and YY 0969-2013 disposable medical mask.
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.
