Masks Bacterial Filtration Efficiency (BFE) Tester

mask bacterial filtration efficiency (BFE) tester is used to quickly and accurately detect Bacterial Filtration Efficiency (BFE) of various flat masks, 3D masks, and protective materials. This product is developed strictly following the Attachment B in YY0469-2011 "Medical Surgical Mask", Bacterial Filtration Efficiency (BFE) experimental method.
The product uses highly integrated design, intelligent control technology. It also conforms to ASTMF2100, ASTMF2101 and EN14683.
It is used to test the percentage of materials containing bacteria suspended particles at the specified flow rate. The dual gas path simultaneous comparison sampling method is used to improve the accuracy of sampling, which is suitable for the performance testing of bacterial filtration efficiency of medical surgical  by metrological inspection departments, scientific research institutes, medical mask manufacturers and other relevant departments.
