Filter Efficiency Tester Manufacturer

Description :

　　The box type observation window of the bacterial filtration efficiency detector is designed with a safe operating port for easy operation and observation of the testing process. The head mold is made of metal material, which can withstand high temperatures, automatically ignite, and has a long service life.

　　The bacterial filtration efficiency detector is a high-performance intelligent bacterial filtration efficiency detector developed strictly in accordance with the requirements of Appendix B of YY/T0969-2013 and YY0469-2011 "Medical Surgical Masks" for bacterial filtration efficiency experimental methods. It also meets the requirements of ASTM F2100, ASTM F2101, and EN14683. The design system based on negative pressure biosafety cabinet working environment is adopted, 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.
