Masks Bacterial Filtration Efficiency Tester is used to determine the bacterial filtration efficiency (BFE) of medical face masks, surgical face masks, to identify the protective performance from being exposed to bacterial airborne environments, tester can conduct the tests defined in EN 14683, ASTM F2100, ASTM F2101, YY 0469, YY 0969.
10.4-inch high brightness color touch screen, easy to operate.
With USB interface, supporting USB data transmission.
With leakage protection switch, the negative pressure test system and the front opening and closing glass door, that can protect operator safety and provide more convenient way for operator to observe.
Double six stage Anderson sample, compare sampling tests, test result is high accuracy.
The flow of peristaltic pump and the flow rate of microbial aerosol generator can be set.
The inner layer of the cabinet is made of stainless steel, and the outer layer is sprayed with cold-rolled sheet, more stable and reliable.
