STREAM® fluorometer

Operator: Not included

compact multiparameter fluorometer with integrated battery and data logger


The STREAM® fluorometer is a compact multiparameter fluorometer with 3 optical channels for fluorescent tracers (natural fluorescence, Sulforhodamine B, fluorescein/uranine, Amino-G,...), 1 channel for turbidity measurements, and 1 thermometer. The probe has an internal battery and datalogger and with its weight of 1.25kg can easily be taken on the terrain.
Fluorometers can be used for dye tracing in natural river systems or artificial water networks for the analysis of connectivity between water bodies, water flow, residence times of water, turbidity, cyanobacteria concentrations, leakage, sources of pollution, and much more.
