BFE detector popular particle detector

Description :

　　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.

　　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 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.

　　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.
