PhytoFlash™ Submersible Active Fluorometer

PhytoFlash™ is an in situ Submersible Active Fluorometer that can be used to determine the quantum efficiency of phytoplankton in both oligotrophic and mesotrophic environments. The PhytoFlash™ is distinct from other variable fluorescence instruments on the market in that it is the first solid-state instrument capable of variable fluorescence measurements on natural concentrations of phytoplankton. The solid-state platform allows for a much wider range of uses due to the small size, power efficiency, more stable components, and lower price point. 

Product Highlights:

· Real time in situ measurement of phytoplankton photosynthetic parameters

· Operate in three different modes

· Integrate with a CTD

· Self-contained with internal datalogging

· Laboratory mode

· Extended battery life - 30 second intervals for over 35 days

· Large internal data logging memory - 10,000 points
