DZ-526XJ Bacterial Filtration Efficiency Testing

Mask bacterial filtration efficiency (BFE) detector tester ISO/DIS 22611 ASTMF2101 EN 14683 Q/0212 ZRB003 Hot

Summary:

This Mask Bacterial Filtration Efficiency Tester is used to test the percentage of respirator material to remove bacteria-containing suspended particles at a specified flow rate. The method of double air sampling is adopted to improve the accuracy of sampling, which is suitable for the performance test of bacterial filtration efficiency of surgical masks by metrological verification departments, scientific research institutes, medical mask manufacturers and other relevant.

Face Masks bacterial filtration efficiency BFE tester is to determine the bacterial filtration efficiency (BFE) of medical face mask materials by employing a ratio of the upstream bacterial challenge to downstream residual concentration of the tested medical face mask materials.
