Description

The Submersible Ultraviolet Nitrate Analyser (SUNA) uses ultraviolet absorption spectroscopy to measure in-situ dissolved nitrate. It is a chemical-free method that allows real-time and continuous nitrate concentration measurements in a variety of environments. It has a 1 cm path length, 190 - 370 nm wavelength range and a depth rating of 100 m.
