通氣阻力及壓力差測試儀
產品介紹：
通氣阻力及壓力差測試儀-用來對通氣阻力及壓力差的測定，也可用來測定其它紡織材料的氣體交換壓力差。也可用于廠、勞動防護用品檢驗機構對產品進行相關的檢測和檢驗。
The mask ventilation resistance and pressure difference tester is used to measure the ventilation resistance and pressure difference of the mask, and also to measure the gas exchange pressure difference of other textile materials. It can also be used for the inspection and inspection of mask products by mask manufacturers and labor protection equipment inspection organizations.
測試原理：
通過氣體流量計設定氣流的輸出，使該氣流經過一定面積的測試樣品，通過壓力傳感器檢測當前壓力并計算壓力差
Set the output of the air flow through the gas flowmeter, make the air flow pass through a certain area of test sample, detect the current pressure through the pressure sensor and calculate the pressure difference
