A simple, high-precision, multi-functional self-contained underwater fluorometer.WETStar fluorometers provide accurate measurements of chlorophyll fluorescence in ambient water bodies with high sensitivity.Chlorophyll fluorescence is used as a factor in the aquatic aggregation level to estimate the activity of biomass in water bodies.

wet starThe new flow cell design is adopted to avoid the impact of ambient light fluctuations. The shell material adopts an advanced engineering anti-corrosion design and can be placed in water for a long time for measurement.The control program can preset the sampling interval of the instrument;Utilize automatic range control,Instruments can be applied under complex conditions,Able to adapt to drastic dynamic changes,Profile measurements can be performed,Fixed-point measurements can also be performed.7–15 VD CInput voltage range, and0–5 VD CAnalog output allows the fluorometer to be integrated with existing CTD systems.
