Mask BFE Testing Machineis used to test the percentage of material containing bacterial suspended particles at a specific flow rate.
Features:
1. MaskBFE Testing Machine: negative pressure test system, can protect the safety of the operator.
2. Peristaltic pump built in the negative pressure cabinet,A, B channel 28.3L/min.
3. The flow rate of the peristaltic pump can be set.
4. BFE Tester atomization effect is good.
Mask BFE Testing Machinetest principle:
Bacterial filtration efficiency Tester consists of aerosol generation system, aerosol chamber and aerosol transmission device, negative pressure cabinet, 28.3 l/min carbon sampler and other components.The entire detector is controlled by the console.
Bacterial filtration efficiency Tester consists of aerosol generation system, aerosol chamber and aerosol transmission device, negative pressure cabinet, 28.3 l/min carbon sampler and other components.The entire detector is controlled by the console.
The console adopts microcomputer control system to coordinate and control the work of aerosol generating system, transmission system, negative pressure cabinet and sampling system, and display the working status in real time.The entire measurement work is done automatically.
