Product Introduction:
The blue-green algae sensor operates based on fluorescence detection, measuring blue-green algae concentration by detecting the intensity of the emitted fluorescence.Blue-green algaesensors are widely used for environmental monitoring of algal growth, phytoplankton, in river sections, lakes, reservoirs, and coastal areas.
Product Features:
Fast measurement speed, high sensitivity, and good selectivity.
Samples do not require processing or extraction, non-destructive, reagent-free, and pollution-free.
Features a self-cleaning function to remove adhered substances from the water sample, maintenance-free.
Corrosion-resistant housing with an IP68 waterproof rating, suitable for long-term underwater operation.
Automatic temperature compensation.
Stainless steel housing, corrosion-resistant, suitable for long-term online monitoring use.
