Particulate filtration efficiency (PFE) tester is suitable for rapid, accurate and stable detection of the filtration efficiency of various medical and daily protective masks, respirators, etc.
1.Flow detection: The system test flow is mainly provided by dry and clean compressed air from the outside. Internal voltage stabilization and flow stabilization devices to ensure the stability of the detected flow, and the automatic control system is simple, fast and stable.
2.Test results: equipped with 7-inch touch screen, the test results are displayed directly on the interface, the user can choose to directly or save the data.
3.Data port: external memory card, export data without worrying about data loss.
4.Resistance detection: The resistance pressure difference of the filter material will be obtained through the static pressure ring of the upstream and downstream test chambers, adopt high-precision imported brand differential pressure transmitter to ensure the accuracy and stability of differential pressure.
5.Simple operation: the user only needs to place the filter paper in the fixture and press the button to adjust the test flow, the system will automatically test the resistance and efficiency through the controller (PLC).
