Features:
1. Double channel, double generator, double counter, salt and oil aerosol channel separation technology;
2,0.3um, 0.5um, 1.0um, 2.5um, 5.0um, 10.0um particle filter efficiency display.
3. Aerosol generation: The Collision multi-nozzle design enables salt and oil testing on the same instrument to ensure fast and stable adjustment of the fogging concentration;
3.Equipped with a 10-inch touch display screen, the test results are directly displayed on the interface, the user can choose to print, export or save directly;;
4.Efficiency detection: The brand high-precision dust particle counter is used to detect the concentration of upstream and downstream particles to ensure accurate and stable sampling;
5. Flow detection: The system test flow mainly provides dry and clean compressed air from the outside. There is a voltage-stabilizing and stabilizing device installed inside to ensure the stability of the detection flow, and the automatic control system is simple, fast and stable.
6. Resistance test: The resistance pressure difference of the filter material will be obtained through the static pressure ring of its upstream and downstream test chambers, and a high-precision imported brand pressure difference transmitter is used to ensure the accuracy and stability of the pressure difference;
7. Simple operation: The user only needs to place the filter paper in the fixture and press the button. After adjusting the test flow, the system will automatically test the resistance and efficiency through the controller (PLC). The whole process is simple, fast and efficient.
