Application:

The main performance indicators of the mask bacterial filtration efficiency (BFE) tester not only meet the requirements of the B.1.1.1.1 test instrument of the B. BFE test method in Appendix B of Medical Surgical Mask Technical Requirements HY0469-2011. The American Society for Testing Materials ASTMF2100. ASTMF210K European EN14683 standard requirements, and based on this innovative improvement, the use of dual gas path simultaneous sampling method to improve the accuracy of sampling, suitable for metrological inspection departments, research institute Performance test of mask filter efficiency by the institute, mask manufacturers and other related departments.
