Abstract
We report experimental results from a flow-through integrating cavity absorption meter. The operating range of the device is from to over of absorption. Absorption coefficients have been measured with 8% or less change in the presence of over of scattering in the medium. The instrument signal has been shown to be independent of flow rate up to and thus independent of turbulence. This large operational range along with the ability to measure absorption independently of adverse scattering affects allows the instrument to be utilized in a wide range of environmental conditions.
