Blue Green Algae Sensor

blue-green algae sensor submersible fluorometer Hydrolab based on the Turner Designs Cyclops-7

The blue-green algae sensor from Hydrolab is based on the Turner Designs Cyclops-7 submersible fluorometer.  Two versions are available, one for phycocyanin and one for phycoerythrin.


  • Available in two forms, one for detecting phycocyanin (fresh water), and one for detecting phycoerythrin (marine water)
  • Available with solid Secondary Standards to provide a quick and simple method to verify the sensor’s stability over time, and can be adjusted to correlate to a known Blue-Green Algae concentration
  • Three auto-selected gain ranges provide a wide measurement range of 100 to 2,000,000 cells/mL for either phycocyanin or phycoerythrin
  • Excellent turbidity rejection due to small sample volume design and high quality optical filters
