Online Chlorophyll Sensor
HydroMetric chlorophyll sensor uses in-situ fluorescence to estimate chlorophyll-a concentration for rapid online monitoring without sample extraction. It is suited to source-water, aquaculture, surface-water and marine monitoring where early indication of phytoplankton activity is important.

- Seawater and coastal monitoring with suitable material selection
Installation & Integration
Fluorescence signals can vary with algae distribution and water matrix. Use representative placement and, where blooms are spatially uneven, consider multi-point monitoring. Confirm water type and required material before ordering.
