Abstract:
A device and process to measure the water content of a material or the water permeability of a membrane by stably humidifying a carrier gas stream and passing it through calcium carbide to convert the water content of the stream to acetylene, then producing a spectrographic or equivalent trace establishing the stable acetylene value of the carrier gas, then passing carrier gas into contact with the material whose water content is to be measured to evaporate water from it and passing the carrier gas through the calcium carbide whereby the water content of the material is represented by the area between the stable acetylene value and the spectrographic trace caused by the added water.
