Features

Phycocyanin fluorescence for early blue-green algae bloom warning

Characteristic phycocyanin fluorescence identifies cyanobacteria and complements chlorophyll-a for better algal-population discrimination. An optional self-cleaning brush limits fouling for stable, unattended source-water monitoring.

Advanced Circuitry

High StabilityFluorescence Circuit,PhycocyaninFluorescence SignalHigh-precision Acquisition.

Easy Installation

Submersion and flow-through options with a standard cable for buoy or shore deployment.

Industrial-grade Protection

IP68 protection with a weather-resistant housing and optional self-cleaning brush to limit biofouling.

Fast Response

Fast fluorescence response, low drift, and stable long-term online operation.
