SUNA Sumersible Ultraviolet Nitrate Analyzer

The SUNA is a cost-effective solution for real-time nitrate analysis in coastal and freshwater environments, providing quick and continuous nitrate measurements. The SUNA uses ultraviolet absorption spectroscopy to measure in-situ dissolved nitrate, it does not require reagents.
The SUNA has been designed with a variety of telemetry interfaces to ensure easy integration into existing water monitoring systems. SUNA is provided with a WindowsT based software package (SUNACom) for easy set-up, operation, and in-field calibration.
