The SUNA V2 is the ultimate solution for real-time nutrient monitoring. This
sensor measures nitrate with industry leading accuracy and stability over a wide
range of environmental conditions (including extremely turbid and high CDOM
conditions), from blue-ocean nitraclines to storm runoff in rivers and streams.
The SUNA V2 incorporates the proven MBARI-ISUS nitrate measurement
technology, which is based on the absorption characteristics of nitrate in the UV
light spectrum.
Features
• Accuracy and stability over a wide range of environmental conditions* • Adaptive sampling intelligence
• Universal real-time nitrate processing algorithm • 10 or 5 mm pathlength • Serial data output and a 500 meter depth rating
• Titanium housing • User-friendly UCI software (Windows and Mac OS X compatible)
