Satlantic’s ISUS V3 nitrate sensor is a real time, chemical free sensor designed to overcome the traditional challenges associated with reagent-based nitrate analysis in aquatic environments. The ISUS technology uses advanced UV absorption technology to provide accurate nitrate concentration measurements in real-time.

Applications:

  • Long term nitrate monitoring
  • Water quality assessment in estuaries and coastal environments
  • Freshwater nutrient loading studies
  • Watershed TMDL assessment
  • Phytoplankton bloom prediction
  • Wastewater monitoring

The MBARI-ISUS technology was developed by Dr. Kenneth Johnson  and Mr. Luke Coletti of the Monterey Bay Aquarium Research Institute and published as Johnson and Coletti 2002, In situ ulrtaviolet spectrophotometry for high resolution and long-term monitoring of nitrate, bromide and bisulfide in the Ocean.

The new ISUS V3 now comes with full speed USB capability and the ISUSCom windows-based software package.  ISUSCom
allows users to log and view real time data, download files, set sampling schedules, and much more all through an easy to use interface. (MBARI).
