SJ-X100 Masks filter test BFE tester , Laboratory BFE Detector
This Mask Bacterial Filtration Efficiency Tester is used to test the percentage of respirator material to remove bacteria-containing suspended particles at a specified flow rate. The method of double air sampling is adopted to improve the accuracy of sampling, which is suitable for the performance test of bacterial filtration efficiency of surgical masks by metrological verification departments, scientific research institutes, medical mask manufacturers and other relevant.
