The Pixie™

4-Channel Fluorometer

Tiny, Low-power 4-Channel Fluorometer with Configurable Filters to Suit Your Sensing Requirements

Moored in place, towed behind a ship or attached to an AUV, the PIXIE™ fluorometer from Dartmouth Ocean Technologies can measure 4 independent fluorescence signatures of the environment in a single deployment. The unit can log and stream data for Chlorophyl-a, phycocyanin, phycoerythrin (rhodamine), and FDOM/crude oil.
