A method and apparatus for monitoring and measuring the level of ion exchange resin fragments in very pure water employs a laser light source to illuminate a water sample causing the resin fragments to fluoresce. This light of fluorescence is focused, filtered, and detected by a photodetector, whose electrical signal output is amplified and processed to provide an output related to the concentration of ion exchange resin fragments in the water. Separate calculations or a computer within the apparatus itself produce a measure of the concentration of the resin fragments in the sample. The apparatus and method are useful for maintaining purity of water in boilers employing condensate polisher systems, for example.
