Kilroy is a water-quality monitor unlike any other. Hardly larger than a football, at a fraction of the cost of other sensors, Kilroy monitors the physical, chemical and biological indicators of health in a particular body of water and it does so, 24 hours a day, 365 days a year.

A fully loaded Kilroy system measures:

  • Depth
  • Water Temperature
  • Salinity
  • Conductivity
  • Water Temperature
  • Flow speed
  • Flow direction
  • Dissolved oxygen
  • pH
  • Oxygen Reduction Potential (ORP)
  • Turbidity
  • Chlorophyll
  • Blue Green algae
  • Colored Dissolved Organic Matter (CDOM)
  • Nitrate
  • Phosphate

Kilroys equipped with a meteorological station measure:

  • Rainfall
  • Wind speed
  • Wind direction
  • Air temperature
  • Barometric pressure

Kilroy, as you may remember, was also a WWII legend, appearing as a cartoon character mysteriously scrawled here and there. Everywhere you went, “Kilroy was here." We at ORCA developed this device with the hope that it will soon become as ubiquitous, yet inconspicuous, as Kilroy was. We envision one day hanging our sign above a nation of revitalized and vibrant waters, proudly declaring, ‘Kilroy is here.’
