Filter Cartridge Pore Size Tester
Category:Filter Cartridge Filtration Tester
Introduction
A filter cartridge pore size tester is an industrial testing device primarily used to measure the pore size distribution of filter materials such as filter cloths and membranes. It can output parameters such as maximum pore size, average pore size, and pore size distribution diagrams. Its core principle is based on the gas-liquid or liquid-liquid ejection method, calculating the maximum pore size by detecting the pressure value of bubbles generated when high-pressure side gas penetrates the sample impregnation liquid.
Applications
Filter Cartridge Pore Size Tester is widely used in fields such as determining the effective pore size of geotextiles, testing filter performance, and analyzing the pore structure of catalysts. It complies with standards such as ISO2942-2004 and GB/T14041.1-2007. and features resistive touchscreen operation, temperature compensation, and data storage capabilities. It supports rapid testing and applications in multiple scenarios.
