6.2.2 Pay attention to the change in the value displayed by the resistivity meter. When the outlet water resistivity rises back to 10M2·cm, the timing ends. 6.3 Initial flow test
6.3.1 Install the unit filter element (length is 254mm) on the special filtering equipment and pass pure water (or distilled water). The hydrophobic filter element needs to be soaked with isopropyl alcohol (or anhydrous ethanol) in advance; 6.3.2 Pressure (using a precision pressure gauge with an accuracy level of 0.4 and a range of 0MPa to 0.4MPa) so that the pressure difference between the inside and outside of the filter element reaches 0.02MPa;
