Product Introduction
The Bacterial Filtration Efficiency (BFE) Tester (product model SUP_XJXT) is a high-performance intelligent bacterial filtration efficiency tester developed in strict accordance with the experimental method requirements for BFE in Appendix B of YY/T0969-2013 and YY0469-2011 "Medical Surgical Masks". It also meets the requirements of ASTM F2100, ASTM F2101, and EN14683. The design system based on negative pressure biosafety cabinet working environment is adopted, which is safe and convenient to use, and the quality is controllable. The method of simultaneous comparison sampling with dual gas paths has accurate sampling and high detection efficiency. Adopting a touchable color industrial resistive screen, it can be easily operated in various situations. Applicable to performance testing of mask bacterial filtration efficiency by inspection and quarantine units, metrological verification departments, research institutes, mask production, and related departments.
