Product Description
HZ-9514 Bacterial Filtration Efficiency Tester (BFE)
Equipment Overview
It used to test the percentage of respirator material removed from the bacteria - containing suspended particles at a specified flow rate. The dual-air path sampling method improves the accuracy of sampling, which is applicable to the performance test of bacterial filtration efficiency of medical surgical masks by metrological verification departments, scientific research institutes, medical mask manufacturers and other relevant departments
