UniLux is a low cost, miniature fluorometer for monitoring Chlorophyll a, other algae pigments, and common tracer dyes. The highly sensitive sensors indicate small changes in the parameters at very low concentrations.


Features & Applications


  • Highly sensitive miniature fluorometer
  • Low cost solution for algae monitoring and dye detection at low concentrations
  • Real-time data output in μg/l
  • User configurable sampling frequency from 0.1 Hz to 3 Hz
  • Robust ambient light and turbidity rejection
  • Data display and logging with Hawk and Watchkeeper accessories


  • In situ chlorophyll & algae class studies
  • Monitoring within water treatment plants
  • Taste & odour issues
  • Environment & water quality monitoring
  • Monitoring spatial & temporal changes in algae class composition
  • Early warning of bloom detection
  • Dye tracing
  • Particulate studies
  • Process control
  • Integration within marine CTDs, AUVs and towed vehicles
