Membrane Pore Size Analyzer NMPA-100 supports wide pressure ranges with a minimum reading of 0.005 MPa. It uses a bubble point method to determine membrane pore sizes with high accuracy. Our stainless-steel housing ensures easy cleaning and long-term durability. This is compatible with membrane filters that accept both air and nitrogen as pressure sources. It is designed for precision and repeatability, simplifying membrane quality verification in laboratory settings.
