DRK-1000 Mask bacterial filtration efficiency (BFE) tester

The main performance indicators of the DRK-1000 mask bacterial filtration efficiency (BFE) detector not only meet the requirements of the test instrument in Appendix B of the YY0469-2011 Bacterial Filtration Efficiency (BFE) Test Method, but also meet the requirements of the American Society for Testing and Materials ASTMF2100, ASTMF2101, and European EN14683 standards require innovative improvements based on the requirements of ASTMF2100, ASTMF2101, and European EN14683 standards. The use of dual gas circuits simultaneously contrasts the sampling method to improve the accuracy of sampling.
