28.3 L/Min Medical Material Tester Bacterial Filtration Efficiency (BFE) Test Chamber
Products 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.
