  • Opis
  • WKS-1010 Mask Bacterial Filtration Efficiency (BFE) Tester is used to test the percentage of the mask material to filter out the suspended particles containing bacteria under the specified flow rate. It is suitable for the performance test of the bacterial filtration efficiency of medical surgical masks by metrological inspection departments, scientific research institutes, medical mask manufacturers and other related departments.
