Mask bacterial filtration eficiency detector
Mask bacterial filtration eficiency detector

SH-1000 Bacterial Filtration Efficiency Detector not only conforms to the requirements of medical surgical masks technology YY0469-2011 appendix B in the test method for filter efficiency (BFE) bacteria first b. 1.1.1 test instrument, but also conforms to the American society for testing material ASTMF2100, ASTMF2101, the requirements of the European EN14683 standards, innovative improvements were made on the basis of this, with double pneumatic contrast sampling method at the same time, improve the precision of sampling,It is suitable for measuring and testing departments, scientific research institutes, mask manufacturers and other relevant departments to test the performance of mask bacterial filtration efficiency.
