ABSTRACT:
In optical analysis of fluids a method and an apparatus are described by which it is possible to continuously measure the concentration value of the fluid within a very broad range of concentration values. In one single test glass optical paths of different lengths are provided substantially perpendicularly to each other. The concentration value of the fluid is measured simultaneously along the two mutually perpendicular optical paths.
