China Respiratory Resistance Tester manufacturers Mask & Respirator Breathing Resistance Tester
Application
Mask & Respirator Breathing Resistance Tester can be used to determine the inspiratory and expiratory resistance of masks under specified conditions. Another additional function of this machine is flow impact test of the breather valve. The flow rate for inhale resistance test is 30L/min and 95L/min. The flow rate for exhale resistance test is 160L/min. And the flow rate for the flow impact test is 300L/min.
