Features: 1. Dual particle counter, simultaneous detection before and after filtration (photometer method is optional) 2. 0.3um, 0.5um, 1.0um, 2.5um, 5.0um, 10.0um particle size particle filtration efficiency display; 3. Equipped with a 7-inch touch screen, the test results are directly displayed on the interface, and the user can choose to print, export or save directly; 4. Efficiency detection: Imported brand high-precision dust particle counter or photometric particle test meter is used to detect the upstream and downstream particle concentration to ensure the accuracy and stability of sampling; 5. Flow detection: The system test flow is mainly provided by external dry and clean compressed air. There is a voltage stabilization device installed inside to ensure the stability of the detection flow, and the automatic control system is simple, fast and stable. 6. 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, and the high-precision imported brand pressure difference transmitter will be used to ensure the accuracy and stability of the pressure difference; 7. Simple operation: the user only needs to place the sample in the fixture, press the button, adjust the test flow, and the system will automatically test the resistance and efficiency through the controller.
