GBN701 Hood ventilation resistance and pressure difference tester


GBN701 Medical Mask Ventilation Resistance and Pressure Difference Tester Application:

It is suitable for measuring the ventilation resistance and pressure difference of medical hoods, and can also be used to measure the gas exchange pressure difference of other textile materials.

Product principle:

The output of the airflow is set by the gas flow meter, so that the airflow passes through a certain area of ​​the test sample, the current pressure is detected by the pressure sensor and the pressure difference is calculated.
