KN95 particle detector equipment

Description :

　　The main purpose of the bacterial filtration efficiency tester is to use a dual gas path simultaneous comparative sampling method to improve the accuracy of sampling. It is suitable for performance testing of mask bacterial filtration efficiency by metrological verification departments, research institutes, mask production enterprises, and other related departments.

　　Application of Bacterial Filtration Efficiency Tester:

　　It is mainly used to test the combustion performance of medical masks after being exposed to flames at a certain linear velocity, and is a flame retardant performance testing instrument for medical masks. The instrument is also suitable for performance verification of new products in research and development, quality control in production departments, third-party testing institutions, product performance verification laboratories, quality and technical supervision departments, etc., to determine material properties.

　　Performance characteristics of bacterial filtration efficiency detector:

　　1. The use of a cold gas aerosol generator produces continuous and stable aerosol particles, making it easy to add the solution;

　　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 bacterial filtration efficiency detector is a high-performance intelligent bacterial filtration efficiency detector developed strictly in accordance with the requirements of Appendix B of YY/T0969-2013 and YY0469-2011 "Medical Surgical Masks" for bacterial filtration efficiency experimental methods. It also meets the requirements of ASTM F2100, ASTM F2101, and EN14683. The design system based on negative pressure biosafety cabinet working environment is adopted, which is safe and convenient to use, and the quality is controllable. The method of simultaneous comparison sampling with dual gas paths has high sampling and detection efficiency. Adopting a touchable color industrial resistive screen, it can be easily operated in various situations. Applicable to performance testing of mask bacterial filtration efficiency by inspection and quarantine units, metrological verification departments, research institutes, mask production, and related departments.
