Mask Respirator Breathing Resistance Test Machine GB2626 Automatically Testing

Mask & Respirator Breathing Resistance Test Machine

MODEL: SM 4309A

Respirator Breathing Resistance Tester is used to test the inhalation resistance and exhalation resistance of respirators and masks under certain condition.

Wear the tested sample on the matching head mold in an airtight way, adjust the ventilation to (85 ± 1) L/min, measure and record the maximum inhalation resistance; then test the exhalation resistance of the tested sample with the same ventilation.

SM4309A tester, built-in adjustable air pump, inhalation and exhalation, two sets of pipeline system, flow sensor and other respiratory resistance measuring devices; The system can automatically control the ventilation volume, and automatically measure the inhalation and exhalation resistance.

Testing Scope: facemasks, Dustproof masks, Medical masks, Anti-haze masks, etc.

Testing Standards:

Specification:

1. The measuring range of flowmeter is 0-100L/min, and the accuracy is ± 2%;

2. The range of the micro manometer is -1000Pa ~ 1000Pa, the accuracy is 1%, and the resolution is 1Pa;

3. Pumping capacity of air pump: no less than 100L/min;

4. Ventilation capacity: 30L/min, 40L/min, 85L/min, 95L/min, settable.
