Mask Bacterial Filtration Efficiency Tester(BFE)
Bacterial Filtration Efficiency Tester is used to detect various medical and daily protective mask materials and filter out the percentage of bacteria-containing suspended particles (BFE) under the specified flow rate.
Bacterial Filtration Efficiency Tester is composed of aerosol generating system, aerosol chamber and aerosol transmission device, negative pressure cabinet, 28.3L / min C sampler, etc. 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.
YY0469-2004,YY/T 0969-2013,ASTMF2100,ASTMF2101,EN14683 ect.
Negative pressure test system to ensure the safety of operators.
The negative pressure cabinet has a built-in peristaltic pump, A and B two-way six-stage Anderson.
The flow rate of the peristaltic pump can be set according to the situation.
The flow rate of the bacterial liquid mist of the special microbial aerosol generator can be set, and the atomization effect is good.
Industrial microcomputer control.
High-brightness color touch screen.
USB interface, support U disk data transfer.
Built-in high-brightness lights. Easy to observe.
Built-in built-in leakage protection switch to protect the safety of operators.
The front glass door is convenient for the operator to observe the operation.
