Description:
1. It executes ISO2942 and ISO4003 standards. One side of filter media is infiltrated by test liquid and submerged according to the specified height.
2. The other side is micro-pressurized by dry air. When the air current passes through the filter layer and the pressure is larger than the other face, the bubble will overflow.
3. The first bubble is the maximum pore size of filter media, and the group of bubbles is general pore size.
4. The pore size of filter media can be calculated according to the micro-pressure value of bubbling.
