Viral filtration efficiency testing machine ZR-1000

for masksfor laboratoriesfor research and development

The main performance indexes of ZR-1000 mask bacterial filtration efficiency (BFE) tester not only meet the requirements of test instrument B.1.1 in Appendix B of technical requirements for medical surgical masks (YY0469-2011), but also meet the requirements of ASTMF2100, ASTMF2101 and European EN14683, On this basis, the innovative improvement is carried out, and the method of double gas path simultaneous comparison sampling is adopted to improve the accuracy of sampling, which is applicable to the performance test of the bacterial filtration efficiency of the mask by the metrological verification department, scientific research institutes, mask manufacturers and other relevant departments.
