The bacterial filtration efficiency tester is suitable for surgical masks: it is used to cover the user’s mouth, nose and jaw, and to provide physical barrier to prevent the direct transmission of pathogens, microorganisms, body fluids, particles, etc. The bacterial filtration efficiency tester adopts the method of double-air sampling at the same time to improve the accuracy of sampling. It is suitable for the performance test of bacterial filtration efficiency of masks by metrological verification departments, scientific research institutes, mask manufacturers and other relevant departments. It is composed of aerosol generation system, aerosol chamber and aerosol transmission device, negative pressure cabinet, 28.3L/min sampler, etc. The whole detector is unified controlled by the console. The console adopts microcomputer control system to coordinate and control the work of aerosol generation system, transmission system, negative pressure cabinet and sampling system, and displays the working state in real time, and the whole measurement work is completed automatically.
Bacterial filtration efficiency tester technical characteristics:
1, Professional negative pressure biological cabinet safe working environment, to ensure the safety of operators
2, High negative pressure working chamber, two stage hePA filter, 100% safe discharge
3. Two-channel and six-level Anderson sampling is adopted.
