Aquaculture Pond Water Chlorophyll Detector Underwater Algae Monitoring Sensor

Fiber-optic design combined with built-in optical filtering algorithm blocks sunlight and facility lighting from interfering with fluorescence readings in outdoor open-water deployments.

Integrated self-cleaning brush actively clears air bubbles and biological deposits from the optical window, maintaining measurement accuracy in turbid water.

Simultaneous output of both ug/L concentration and RFU values allows users to cross-reference raw fluorescence intensity against calibrated chlorophyll concentration in a single reading.

Single-cell resolution across a 0 to 300,000 cells/mL range enables early warning detection of cyanobacteria blooms at concentrations far below levels detectable by traditional manual counting.

Near-perfect linearity across the full measurement range ensures output signal proportionality to actual cell concentration, minimizing calibration correction requirements across varying bloom densiti

Built-in temperature transmitter with plus or minus 0.5 degrees C accuracy enables real-time compensation.

Full IP68 waterproof protection and 0.6MPa pressure tolerance support continuous submersion in rivers, lakes, reservoirs, and coastal survey points without housing degradation over time.

Fluorescence-based optical sensing eliminates all consumable reagents, enabling indefinite unattended operation without per-test material costs or chemical handling in remote field installations.

Recommended 3-month calibration interval using Rhodamine B reference solutions at defined concentrations keeps accuracy verified without frequent site visits in stable environments.

Broad voltage tolerance across 7 to 30VDC with only 0.4W power draw supports solar or battery-powered deployment in remote lakes, fish ponds, and drinking water source monitoring stations.
