Micro-Filtration Membrane Porometer
Based on the capillary flow (bubble point) method, this instrument automatically measures the pore size distribution of various microfiltration materials, including filter paper, carbon paper, porous ceramics, sintered metals, polymer membranes, woven and non-woven fabrics, and glass filters. With a measurement range of 0.01–100 μm, it accurately identifies effective pore throat size and diameter while avoiding interference from blind pores
- Testing pressure: 0~3.5 Mpa
- Testing flowrate: 0~200 L/min.
