　　2. Using high-precision laser sensors to measure aerosol concentration;

　　3. Full process particle leakage prevention design to protect the safety of experimental personnel;

　　4. Two sets of aerosol generators: saline particulate aerosol generator and oily particulate aerosol generator;

　　5. Pneumatic fixture with protective device, safe and convenient to use;

　　6. Configure precision flow meters and laser dust particle counters;

　　7. Filter efficiency detection range: 0-99.999%;

　　8. Filter efficiency detection flowmeter range (10-100) L/min, accuracy level 2.5;

　　9. Control system: friendly human-machine interface controls the testing process and automatically collects data;

　　10. The system automatically tests gas concentration and calculates filtration efficiency; Can save, output, query, and print test data;

　　11. Color touch screens are easier to operate.

　　The technical features of the bacterial filtration efficiency detector include a negative pressure experimental system to ensure the safety of operators, and the flow rate of the peristaltic pump can be set; The cabinet is equipped with built-in lighting and a leakage protection switch. The inner layer of the cabinet is made of stainless steel and processed as a whole, while the outer layer is made of spray coated cold-rolled sheet. The front switch type glass door has a detachable bracket with adjustable height; Mobile dual-use wheels.

　　Instructions for Bacterial Filtration Efficiency Tester: The main performance indicators not only comply with the requirements of Appendix B Bacterial Filtration Efficiency (BFE) Test Method B.1.1.1 of the "Technical Requirements for Medical Surgical Meltblown Filter Media" YY0469-2011, but also meet the requirements of the American Society for Testing and Materials ASTMF2100, ASTMF201, and European EN14683 standards. Based on this, innovative improvements have been made, using a dual gas path simultaneous comparative sampling method to improve the accuracy of sampling. It is suitable for performance testing of bacterial filtration efficiency of meltblown filter media by metrological inspection departments, research institutes, meltblown filter media production enterprises, and other relevant departments.
