Face Mask Bacterial Filtration Efficiency Tester

Application
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 masks by metrological inspection departments, scientific research institutes, medical mask manufacturers and other relevant departments.

Standards
ASTMF2100, ASTMF2101, EN14683
