mask bacterial filtration efficiency (BFE) tester is used to quickly and accurately detect Bacterial Filtration Efficiency (BFE) of various flat masks, 3D masks, and protective materials. This product is developed strictly following the Attachment B in YY0469-2011 "Medical Surgical Mask", Bacterial Filtration Efficiency (BFE) experimental method.
 
The product uses highly integrated design, intelligent control technology. It also conforms to ASTMF2100, ASTMF2101 and EN14683.
 
1. Negative pressure experiment system to ensure the safety of operators.
2. Built-in peristaltic pump in negative pressure cabinet, A, B two-way six-stage Andersen.
3. The flow rate of the peristaltic pump can be set.
4. Special bacterial liquid sprayer, the spray flow size can be set, and the atomization effect is good.
5. Embedded high-speed industrial microcomputer control.
6, 10.4-inch industrial-grade high-brightness color touch display.
7, USB interface, support U disk data transfer.
8. Software parameter calibration.
9. User password protection.
10, fault detection self- / 2 protection.
11. The cabinet has built-in high-brightness lighting.
12, built-in leakage protection switch to protect the safety of operators.
13. The inner stainless steel of the cabinet is integrally processed and formed, and the outer layer is spray-coated with cold-rolled sheet. The inner and outer layers are insulated and flame retardant.
14. The front switch glass door is convenient for experimenters to observe and operate.
15. Detachable stand, height of stand is adjustable.
16. Support and move dual-purpose casters.
