Abstract
An improved spectroscopic hygrometer includes a krypton-filled source tube that produces emissions at 123.58 nm for selective absorption by water vapor in a gaseous sample. The method for measuring water vapor density requires generation of ultraviolet radiation from a krypton source, receipt of the radiation by a detector, and passage of a gaseous sample through the radiation that is directed to the detector. The krypton radiation has been found to be an effective source for hygrometry purposes, and a practical improvement over prior hydrogen sources.
