Introduction: The GL3250 type mask bacterial filtration efficiency (BFE) detector is strictly in accordance with the requirements of YY/T0969-2013, YY0469-2011, ASTMF2100, ASTMF2101, and European EN14683 standards. The design system based on the working environment of the negative pressure biological safety cabinet is adopted, which is safe and convenient to use and the quality is controllable. The method of simultaneous comparison and sampling of dual gas paths has the advantages of accurate sampling and high detection efficiency. With touchable color industrial resistive screen, it can be easily operated in various situations. It is suitable for performance testing of inspection and quarantine units, metrological verification departments, scientific research institutes, mask production and related departments on the bacterial filtration efficiency of masks. Features: 1. Professional negative pressure biological safety cabinet technology to ensure the safety of operators and the environment; 2. High negative pressure working cabin, two-stage high-efficiency filter, 100% safe discharge; 3. Adopt two-way six-level Anderson precise sampling; 4. Built-in peristaltic pump, the flow rate of the peristaltic pump is adjustable; 5. Special microbial aerosol generator, the spray flow of bacteria liquid can be adjusted, and the atomization effect is good; 6. Industrial-grade large color touch screen control, easier to operate; 7. RS232/Modbus standard interface (or custom protocol), which can realize external control. 8. The safety cabinet has built-in LED lighting for easy observation; 9. Built-in UV disinfection lamp to enhance the protection effect; Technical parameter: Working temperature: 0~50 ℃ Cabinet negative pressure: > 120Pa Data storage capacity: > 500,000 groups, the capacity can be expanded High efficiency air filter performance: ≥99.995%@0.3μm, ≥99.9995%@0.12μm Dual-channel six-stage Anderson sampler Capture particle size: Class I>7μm, Class II 4.7~7μm, III3.3~4.7μm, IV2.1~3.3μm, V1.1~2.1μm, VI0.6~1.1μm Total number of positive control sampler particles: 2200±500 cfu Aerosol generator mass median diameter: mean particle diameter (3.0 ± 0.3 µm), geometric standard deviation ≤ 1.5 Aerosol Chamber Specifications: Length 600 x Diameter 85 x Thickness 3mm Negative pressure cabinet ventilation flow: >5m3/min Host size: Inner: 870*600*1100mm, outer: 1250*700*2000mm Working noise: < 65db
