摘要: A method and apparatus is provided for measuring the transmission rate of a substance through material, such as packaging film. The during test can be increased, or decreased, by increasing pressure, decreasing respectively, at which conducted. Embodiments use probe that does not consume substance. Specific embodiments utilize flowing gases. Other do require any gas measurement.
