Summary
ECO FL(RT) chlorophyll-A fluorometer measure fluorescence from chlorophyll-a. Chlorophyll-a fluorescence is an indicator of active phytoplankton biomass and chlorophyll concentrations. This measurement is used for tracking biological variability and abundance in the water column.

Components
The fluorometer is installed together with the Valeport Mini SVP in a stainless steel piping system through which sea water taken at 3 m depth is pumped. Calibration factors are integrated in DShip. The fluorometer measures Chlorophyll-a ex/em: 470/695 nm with a resolution of 0.01 µg/l in the range 0.01 to 125 µg/l.
