Disposable mask airflow 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.

The zero point stability of the flow sensor is high, with full range and high stability, high accuracy with full range and excellent repeatability, low power consumption, low pressure loss and fast response speed.
