CF-200 Algae Bloom Monitor
Continuous chlorophyll-A fluorescence monitoring for fresh water and seawater intakes, helping operators identify rising algae concentrations early.
Continuous algae-bloom indication
The CF-200 integrates a C-Fluor probe, bypass assembly, controller and outputs for continuous chlorophyll-A measurement.
01 / MEASUREMENT
Direct chlorophyll-A measurement
The LED-based probe tracks chlorophyll-A without chemicals, reagents or moving analytical parts.
- Seawater measurement range
- Freshwater measurement range
- Long-life LED probe
02 / OPERATION
Early operational warning
Local display, alarm relays and 4-20 mA output help operators respond before algae loading disrupts treatment.
- Two alarm relays
- 4-20 mA output
- Continuous readings
Core CF-200 information
Separate ranges are published for seawater and freshwater using the supplied bypass and isolation assembly.
Ready-to-install assembly
Probe, controller, bypass and backplate arrive integrated.
No analytical chemicals
Fluorescence needs no reagents or moving analytical parts.
Robust water measurement
The probe tolerates bubbles, silt and debris.
Local and remote indication
Use display, relays and 4-20 mA together.
A continuous chlorophyll-A measurement path
A sidestream passes the probe so the system can track algae-related pigment and alert operators.
01.
Deliver the water
Route representative fresh water or seawater through the bypass.
02.
Excite chlorophyll-A
The LED probe applies optical excitation.
03.
Measure emission
The probe detects chlorophyll-A fluorescence.
04.
Display the result
The controller presents the current measurement.
05.
Transmit the signal
A 4-20 mA output sends the result to plant control.
06.
Trigger an alert
Two relays warn when thresholds are reached.
Early algae indication for water-intake protection
Use CF-200 to trend chlorophyll-A as an indicator of algae or plankton loading in fresh water and seawater.

Where the CF-200 can be used
The system suits fresh-water or seawater applications where algae loading affects downstream treatment.
Desalination intake
Trend plankton before pretreatment and membranes.
Fresh-water abstraction
Identify seasonal chlorophyll-A increases.
Industrial cooling intake
Warn where algae can restrict screens or filters.
Chlorophyll-A does not identify every bloom hazard
Use species identification, toxin analysis and statutory monitoring where required.
How does chlorophyll-A fluorescence monitoring work?
The CF-200 excites chlorophyll-A and relates emitted fluorescence to concentration.
Why measure chlorophyll-A?
It is the primary algal pigment and indicates biomass.
Does it need reagents?
No. The C-Fluor probe uses LED fluorescence.
How is the probe maintained?
The bypass and isolation assembly permits removal and cleaning.
