BFE detector Mask detector Types

Description :

　　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 adopts a design system based on negative pressure biosafety cabinet working environment, 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.

　　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.

　　The testing principle of the bacterial filtration efficiency tester is to simulate the actual use state of the mask sample and install it on the head mold rack. The mask passes over the igniter with a constant flame height at a certain linear velocity along with the head mold, observes the combustion of the mask, records the duration of continuous combustion and smoldering, and evaluates whether the mask is qualified.
