The Sailbuoy Water Quality Monitor (WQM) provides the most important marine water quality parameters . The Sailbuoy WQM has been extensively field-tested and demonstrated excellent long-term monitoring.

Sailbuoy WQM is fitted with sensors for water quality measurements. The integrated sensors include the low-drag, fast-response conductivity-temperature sensor manufactured by Neil Brown Ocean Sensors, Inc., an oxygen optode manufactured by Aanderaa Data Instruments, and the C3 Submersible Fluorometer from Turner Designs with up to three optical sensors ranging from the deep ultraviolet to the infrared spectrum. Applications include detection of hydrocarbons, algae or chlorophyll-a activity, water turbidity, dissolved organic matter or chemical dyes.
