Description

Face Mask Bacterial Filtration Efficiency (BFE) Test Chamber

Facial Mask Tester Bacterial Filtration Efficiency (BFE) Test Chamber 28.3 L/Min Sampling Flow

Product overview:

The main performance indicators of the mask bacterial filtration efficiency (BFE) tester not only meet the requirements of B.1.1.1 of YY0469-2011 Annex B bacterial filtration efficiency (BFE) test method, but also comply with the requirements stipulated in American ASTM 2100, ASTMF2101 and European EN14683 standards. Innovative improvements have been made on this basis. The simultaneous sampling method with dual gas channels has been used to improve the accuracy of sampling. It is suitable for the measurement and verification departments, scientific research institutes, mask manufacturing enterprises and other relevant departments to measure the filtering efficiency of mask bacteria.

Equipment Features:

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 Andrsen sampler
3. Flow rate of peristaltic pump can be set
4. The spray flow rate of bacteria liquid of special microbial aerosol generator can be set
5. Good atomization effect
6. Embedded high-speed industrial microcomputer control
7. 10.4 inch industrial-grade high-brightness color touch screen
8. USB interface, support U disk data transfer
9. Built-in high-brightness lighting lamp
10. Built-in leakage protection switch to protect the safety of operators
11. The inner layer of stainless steel is integrally processed and formed, and the outer layer is sprayed with cold-rolled sheet
12. Insulation between inner and outer layers, flame retardant
13. Front opening and closing glass door, convenient for laboratory personnel to observe and operate
14. Removable bracket with adjustable bracket height
15. Support, mobile dual-use casters
