A filter cartridge pore size tester is an industrial instrument used to characterize the pore structure of filtration materials such as filter membranes and filter cloths. It provides key outputs including maximum pore size, mean pore size, and pore size distribution curves. The testing principle is based on gas–liquid or liquid–liquid displacement methods, where the maximum pore size is determined by monitoring the pressure at which the first bubbles appear as pressurized gas passes through a sample saturated with a wetting liquid.

This equipment is widely applied in evaluating the effective pore size of geotextiles, assessing filtration efficiency, and analyzing the pore structure of catalytic materials. It is designed in accordance with standards such as ISO 2942-2004 and GB/T 14041.1-2007. The system typically features a resistive touchscreen interface, temperature compensation function, and integrated data storage, enabling fast testing and flexible operation across multiple application scenarios.
