Medical mask bacterial filtration efficiency (BFE) tester
It is composed of aerosol generation system, aerosol chamber and aerosol transmission device, negative pressure cabinet and 28.3l /min sampler.The whole tester is controlled by the console.The control console adopts microcomputer control system to coordinate and control the work of aerosol generation system, transmission system, negative pressure cabinet and sampling system, and display the working status in real time. The whole measurement work is completed automatically.
Mask Bacterial Filtration Efficiency Tester Features
Double six-stage Anderson microbial sampler test systems with contrast sampling tests provide high accuracy.
Internal aerosol generator provides stable and adjustable microbial aerosol flow. Internal pump can adjust the flow rate.
Equipped negative pressure test chamber to ensure the safety of operators. Equipped light system to make the operations more clear and easy to do.
10.4 Inch touch screen control panel is easy to operate and supports USB data transmission.
Equipped leakage protection and operating window provide better operating view and safety operating conditions.
Stainless steel chamber with insulation and fire retardant lining is stable and reliable.
Mask Bacterial Filtration Efficiency Tester is applied to test the filtration efficiency of mask, can be used in metering calibration department, scientific research institution, mask manufacturer and other related departments.
