Systems and methods for compensated barrier permeability testing are provided. In one embodiment, a method for testing water vapor penetration through a barrier material comprises: obtaining a first series of resistance measurements from a first moisture sensor located on a substrate surface of a test card, wherein the first moisture sensor is exposed to a testing chamber sealed onto the substrate surface of the test card; obtaining a second series of resistance measurements from a second moisture sensor, wherein the second moisture sensor is isolated from the testing chamber, wherein the testing chamber is defined by a cavity within a spacer element that separates the first moisture sensor from a test barrier; and determining a measurement of water vapor penetration through the test barrier by adjusting the first series of resistance measurement based on the second series of resistance measurement.
