Instrument characteristics
1. Efficiency detection: use TSI brand imported brand photometer to detect upstream and downstream particle concentration to ensure accurate and stable sampling;
2. 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;
3. Aerosol generation: Collision multi-nozzle design is adopted, which can conduct salt and oil testing on the same instrument to ensure rapid and stable fogging concentration adjustment;
4. Test results; equipped with a 7-inch touch screen, the test results are directly displayed on the interface, and the user can choose to directly or save the data;
5. Data port: external memory card can export data without worrying about data loss;
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. Data port: external memory card can export data without worrying about data loss;
8. Simple operation: the user only needs to place the filter paper in the fixture, press the button, adjust the test flow, and the system will automatically test the resistance and efficiency through the controller (PLC). The whole process is simple, fast and efficient;
