Masks Bacterial Filtration Efficiency (BFE) Tester is an instrument that tests the ability of the tested sample (such as KOU hood, etc.) to filter out bacteria-containing particles under specified conditions. It is suitable for metrological verification departments, third-party testing, textile industry and fiber raw material industry, etc.

BFE Instrument Features:

1. Negative pressure and closed experimental environment to ensure the safety of operators;

2. Two-way six-level Andersen sampler is used to sample at the same time;

3. There is a built-in peristaltic pump in the sampling chamber, and the flow rate of the peristaltic pump can be set;

4. High-performance gas atomizer, the flow rate can be set;

5. Microbial aerosol generator, good atomization effect;

6. Embedded high-speed industrial microcomputer control;

7.10.4-inch industrial-grade high-brightness color touch display;

8. USB interface, support the use of U disk for data transfer;

9. Support real-time data printing (only for V1.06 and later models);

10. The cabinet has built-in high-brightness lighting and sterilization ultraviolet lamps;

11. Front switch glass door, easy for experimenters to observe and operate;

12. Built-in leakage protection switch to protect the safety of instruments and operators;

13. The inner layer of the cabinet is made of stainless steel as a whole, and the outer layer is sprayed and cold-rolled;

14. The material between the inner and outer layers has thermal insulation and flame retardant properties;

15. Detachable bracket, supporting and moving dual-purpose casters.

The QINSUN Masks Bacterial Filtration Efficiency (BFE) Tester combines industry experience and makes innovative improvements. It adopts the method of simultaneous sampling and comparison of dual gas paths to improve the accuracy of sampling.
