pycnometer Porous Materials Inc. (PMI) specializes in density and porosity measurement technologies, including pycnometer, vacuum pycnometer, and gas-based analysis systems. For users asking what is pycnometer technology, PMI systems measure true density by gas displacement, enabling accurate characterization of porous solids and powders. PMI pycnometry solutions are often paired with oven controlled temperature regulation to minimize thermal effects and improve data stability. Integrated automation and precision pressure measurement ensure repeatable results across materials such as ceramics, metals, polymers, and filtration components.
