Bacterial Filtration Efficiency N95 Tester

Bacterial Filtration Efficiency N95 Tester
Product description
The main performance indicators of the bacterial filtration efficiency (BFE) tester not only meet the requirements of the B.1.1.1 test instrument of Appendix B Bacterial Filtration Efficiency (BFE) Test Methods in Appendix B of the Technical Requirements for Medical Surgical Masks YY0469-2011, but also meet the requirements of the test instrument. The American Society for Testing Materials ASTMF2100, ASTMF2101, and European EN14683 standards, and based on this, innovative improvements have been made. The dual gas path simultaneous comparison sampling method is used to improve the accuracy of sampling. It is suitable for metrological inspection departments and research institutes Performance test of mask bacteria filtration efficiency by laboratories, mask manufacturers and other related departments.
