Particle detector supplied by mask detector manufacturer

Description :

　　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.

　　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.

　　The main configuration of the bacterial filtration efficiency detector is:

　　1. One negative pressure test chamber;

　　2. One set of test stand;

　　3. A set of peristaltic pumps;

　　4. Two sets of flow sensors;

　　5. One set of vortex mixer;

　　6. One set of aerosol generator;

　　7. Two sets of gas collection sensors;

　　8. A set of measurement and control computers;

　　9. One set of experimental software;

　　10. A set of HP color inkjet printers.

　　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.
