Abstract

We report experimental results from a flow-through integrating cavity absorption meter. The operating range of the device is from 0.004 m 1 to over 80 m 1 of absorption. Absorption coefficients have been measured with 8% or less change in the presence of over 200 m 1 of scattering in the medium. The instrument signal has been shown to be independent of flow rate up to 20   liters / min 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.
