Mask Bacterial Filtration Efficiency Detector is used to test the percentage of materials containing bacteria suspended particles at the specified flow rate. 

The dual gas path simultaneous comparison sampling method is used to improve the accuracy of sampling, which is suitable for the performance testing of bacterial filtration efficiency of medical surgical masks by metrological inspection departments, scientific research institutes, medical mask manufacturers and other relevant departments.

Features/Advantages
  • Negative pressure experiment system to ensure the safety of operators;
  • Negative pressure cabinet with built-in peristaltic pump and A and B two-way six-stage Andersen;
  • The flow rate of the peristaltic pump can be set;
  • The dedicated microbial aerosol generator can set the volume of bacterial liquid spray flow, and the atomization effect is good;
