Mask Bacterial Filtration Efficiency (BFE) Detector GT-RA02B
Product Introduction
| Application:
Mask Bacteria Filtration Efficiency Tester,are mainly used for testing the bacterial filtration efficiency performance of masks applicable to metrological verification departments, scientific research institutes, medical mask production units and their related testing departments. It has the characteristics of fast and accurate measurement of the bacterial filtration efficiency of masks [BFE].
The Mask Bacterial Filtration Efficiency (BFE) Detector is composed of a biological aerosol generating system, aerosol chamber, aerosol delivery device, negative pressure cabinet, and 28.3LPM Anderson sampler. The entire detector is controlled by the control system. The console uses PLC+Labview to coordinate and control the work of the aerosol generation system, transmission system, negative pressure cabinet, and sampling system, and displays the working status in real time, and the entire measurement work is automatically completed.
