Instrument characteristics

1. Efficiency detection: Using a branded high-precision dust particle counter to detect particle concentrations upstream and downstream, ensuring accurate and stable sampling;
2. Flow detection: The system tests the flow mainly by providing dry and clean compressed air from the outside. Internally, there is a stable voltage and current device installed to ensure the stability of the detected flow, and an automatic control system is adopted for simplicity, speed, and stability.
3. Aerosol generation: Adopting the Collision multi nozzle design, salt and oil testing can be conducted on the same instrument, ensuring fast and stable adjustment of fog concentration;
4. Test results; Equipped with a 7-inch touch screen display, the detection results are directly displayed on the interface, and users can choose to directly or save data;
5. Data port: External storage 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 rings of its upstream and downstream test chambers, and high-precision imported brand pressure transmitters will be used to ensure the accuracy and stability of the pressure difference; 7. Data port: External storage card, can export data without worrying about data loss; 8. Easy operation: Users only need to place the filter paper in the fixture, press the button, adjust the test flow rate, and the system will automatically test the resistance and efficiency through the controller (PLC). The entire process is simple, fast, and efficient
