Mask Bacteria Filtration Efficiency (BFE) Tester Filter Tester
Mask Bacteria Filtration Efficiency (BFE) Tester is mainly used for the measurement of mask bacterial filtration efficiency performance by metrological verification departments, scientific research institutes, medical mask production units and their related testing departments. 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.
