Mask detector BFE detector types

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.

　　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 mask filtration efficiency testing device is used to test the protective effect and filtration efficiency of daily protective masks and respirators against particulate matter. Applicable to medical device inspection centers, safety protection inspection centers, labor protection inspection centers, drug inspection centers, disease prevention and control centers, textile testing centers, mask and respirator production enterprises, etc.

　　Several technical features of the mask bacterial filtration efficiency detector:

　　1. Key counting module control: digital display counter, can preset 1-99999s time for testing, automatically stops after testing is completed;

　　2. Anti genuine head mold: The mask fixture is a metal human head mold that can fully simulate the actual usage state of the mask;

　　3. High degree of equipment automation: The instrument automatically records the combustion time and flame retardant time, with digital display, equipped with flame temperature measurement probes and flame temperature displays, automatic ignition, and adjustable flame height;

　　4. Negative pressure experimental system to ensure the safety of operators;

　　5. The negative pressure cabinet is equipped with a peristaltic pump, A and B channels of six stages Anderson;

　　6. The flow rate of the peristaltic pump can be set;

　　7. The flow rate of bacteria spray at night of microbial aerosol generator can be set,

　　8. Good atomization effect;

　　9. Embedded high-speed industrial microcomputer control;

　　10. 10.4-inch industrial grade high brightness color touch display screen;

　　11. USB interface, supporting USB data transfer and storage;

　　12. The cabinet is equipped with high brightness lighting fixtures;

　　13. Built in leakage protection switch to protect the safety of operators;

　　14. 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 plate,

　　15. Insulation and flame retardancy between the inner and outer layers;

　　16. Front switch glass door, convenient for experimental personnel to observe and operate;

　　17. Detachable bracket with adjustable height;

　　18. Dual purpose casters for support and mobility.
