50Hz Medical Face Mask Bacterial Filtration Efficiency Tester ASTM Standard
ASTM Standard Medical Mask Bacterial Filtration Efficiency Tester
Product Introduction:
Medical Mask Bacterial Filtration Efficiency Test machine is used to detect various medical and daily protective mask materials and filter out the percentage of bacteria-containing suspended particles (BFE) under the specified flow rate.
It is suitable for the performance testing of bacterial filtration efficiency of medical surgical masks by metrological inspection departments, scientific research institutes, medical mask manufacturers and other related departments.
