Mask respiration resistance tester Respirator Breathing Resistance Tester

Model: RF4309A

The mask breathing resistance tester is used to measure the inhalation resistance and exhalation resistance of respirator and mask protective equipment under specified conditions.

Wear the tested sample on the matching head mold in an airtight manner, adjust the ventilation to (85±1) L/min, measure and record the maximum inspiratory resistance; then test the measured with the same ventilation The breath resistance of the sample;

The RF4309A tester is equipped with a breathing resistance measuring device such as an air pump with adjustable flow rate, two inspiratory and respiratory systems, and a flow sensor. The system can automatically control ventilation and automatically measure breathing and inspiratory resistance.

Scope of application: Ordinary masks, dust masks, medical masks, anti-fog masks, etc.
