Chlorophyll
This chlorophyll fluorometer can provide measurement of the chlorophyll fluorescence within natural waters at a depth rated to 600 meters. The fluorometer comes in an all plastic, corrosion-resistance housing well adapted to marine environment. Knowing that chlorophyll fluorescence is an indicator of phytoplankton concentrations, the use of the fluorometer gives an estimation of biological activity in the water column. The WetStar was designed to be particularly robust to light fluctuations. This instrument operates under an excitation wavelength of 470 nm and an emission wavelength of 685 nm. Its optical sensitivity is 0.03 g/l, in a dynamic range of 0.03 to 75 g/l. It will be mounted on seawater intake system.
