A submersible fluorometer for measuring a fluorescence of a photosynthetic material in a liquid, the fluorometer includes a set of light emitting diodes (LEDs) for supplying light to direct towards the liquid and a photodiode for measuring a detected light emitted from the liquid. The light is used for measuring the fluorescence of the photosynthetic material in the liquid. The fluorometer also has a water-tight volume for protecting the photodiode from the liquid.

Submersible apparatus for measuring active fluorescence

Some embodiments of the invention provide an improved spectrometer that measures light emissions and/or reflection from a non-solid material that flows through a system of pipes. This spectrometer is designed to fit into a standard pipe system. The material flows past a distal end of the spectrometer that is inserted in the pipe system. The spectrometer has the ability to project light onto the material and collect a resulting light from the material through the distal end as the material flows past this end.
