Product Details
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.
Features of BFE filter tester
- Safe working environment, use professional negative pressure
biological cabinet, ensure the safety of operators;
- High negative pressure working cabin, two-stage high efficiency
filter, 100% safe discharge
- Use two-way six-level Anderson sampling;
- Built-in peristaltic pump with adjustable flow rate;
- Special microbial aerosol generator, adjustable spray flow of
bacterial liquid, good atomization effect;
- Industrial grade 10.4-inch color touch screen control, make the
operation is simpler;
- Microcomputer is used for control and data processing, which can be
seamlessly connected to the laboratory information management
system;
- USB interface, support data transfer;
- The safety cabinet has built-in LED lighting for easy observation;
- Built-in ultraviolet UV disinfection lamp;
- The front-opening sealed glass door is convenient for operation and
observation;
- Use imported isolation operation gloves, safe and reliable;
- The system has functions of user authority management and audit
trail;
