Hygrometer, Infrared, Absorption
Saturday, September 09, 2006
A n Infrared Hygrometer has been design and developed using dual wavelength differential absorption. The Hygrometer provides a comparison for correcting drifts in instrument sensitivity, deposits on the windows, hazes, fogs, and other effects to the Hydrometer.
In the folded path version of the Hygrometer, both the infrared source and the detector are isolated from the atmospheric sample within a single hermetically sealed and desiccated enclosure. Infrared radiation leaves and re-enters the enclosure through sealed sapphire windows. In the straight path version, the infrared source and detector are housed in separate enclosures.
