Face Mask BFE Tester ASTM F2101 Medical Lab Testing Equipment
Overview:
Mask Bacterial Filtration Efficiency (BFE) tester is mainly applicable to the measurement of mask bacterial filtration efficiency performance by metrological verification departments, scientific research institutes, medical mask production units and their related testing departments. Mainly meets the requirements of B.1.1.1 test instrument requirements in Appendix B bacterial filtration efficiency (BFE) test method of YY0469-2011 "Technical Requirements for Medical Surgical Masks". It also meets the requirements of ASTM F2100, ASTM F2101, and EN 14683 standards.
Principle
It is composed of aerosol generating system, aerosol chamber and aerosol transmission device, negative pressure cabinet, 28.3L/min sampler, etc., and the entire detector is controlled by the console. The console uses a microcomputer control system to coordinate and control the work of the aerosol generation system, transmission system, negative pressure cabinet, and sampling system, and displays the working status in real time. The entire measurement work is automatically completed.
