Masks Bacterial Filtration Efficiency (BFE) Tester is used for fast, accurate and stable detection of the bacterial filtration effect of medical masks and mask materials. The design system based on the working environment of the negative pressure biological safety cabinet is adopted, which is safe and convenient to use and the quality is controllable. The method of simultaneous comparison and sampling of dual gas paths has high detection efficiency and sampling accuracy. The large screen can touch the color industrial resistive screen, which can be easily controlled even when wearing gloves. It is very suitable for the performance testing of the bacterial filtration efficiency of masks by metrological verification departments, scientific research institutes, mask production and other related departments.
