The main features of the mask particle filtration rate tester are:

1. Dual particle counter, simultaneous detection before and after filtering(Optional photometer method for measurement)

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 detection results are directly displayed on the interface, and users can choose to print, export, or save directly;

4. Efficiency testing: Imported brand high-precision dust particle counters or optical particle testers are used to detect upstream and downstream particle concentrations, ensuring accurate and stable sampling;

5. Flow detection: The system testing flow is mainly provided by dry and clean compressed air from the outside. Internally, there is a voltage and current stabilizing device installed to ensure the stability of the detected flow rate, and an automatic control system is used for simplicity, speed, and stability.

6. Resistance detection: The resistance pressure difference of the filter material will be obtained through the static pressure rings of its upstream and downstream testing chambers, and high-precision imported brand pressure difference transmitters will be used to ensure the accuracy and stability of the pressure difference;

7. Easy to operate: Users only need to place the sample in the fixture, press the button, adjust the test flow rate, and the system will automatically test the resistance and efficiency through the controller. The entire process is simple, fast, and efficient
