TriLux

Low cost, miniature algae sensor that monitors three key algal parameters in a single probe.

TriLux is a low cost, miniature algae sensor that monitors three key algal parameters in a single, highly sensitive probe. The 3-in-1 fluorometer enables widespread monitoring in a variety of applications, including harmful algal blooms, aquaculture, water treatment works, river catchments and coastal studies.

With three different parameter combinations and depth ratings to 2000m, TriLux is suitable for a wide variety of water environments:
• Chlorophyll a, Phycocyanin, Turbidity for freshwater deployments
• Chlorophyll a, Phycoerythrin, Phycocyanin for coastal deployments
• Chlorophyll a, Phycoerythrin, Turbidity for marine deployments

TriLux is compact and easy to integrate in wider systems and platforms including CTDs, data buoys, monitoring stations, AUVs and gliders. Adding the Hawk or Watchkeeper accessories allows real-time data display and logging with portable or wall mounted systems.
