Instruments for measuring water vapor transmission through materials such as polymer films and paper, namely, a cell for holding the film or paper, thereby separating the cell into two chambers, passing a gas containing water vapor into one chamber and measuring the water vapor that passes through the film or paper, by measuring water vapor content in the other chamber
