DESCRIPTION

NOTES

SUNA

SUNA V2 (Submersible Ultraviolet Nitrate Analyzer) with advanced nitrate processing algorithm, adaptive sampling, serial telemetry and USB communications

Depth rating is 500 m, or 100 m if the integrated bio-fouling wiper is selected. Instrument comes with Windows or Mac software package.

SUNA Pathlength Selections – MUST SELECT ONE

SUNA.0xxxx

10 mm optical pathlength

Ideal for low turbidity, low CDOM coastal and oceanic applications

SUNA.1xxxx

5 mm optical pathlength

Reduced pathlength to decrease attenuation of UV light in the sample path, useful in high turbidity (e.g. > 600 NTUs) or high CDOM water

SUNA Anti-fouling Selections – MUST SELECT ONE

SUNA.x0xxx

No wiper

No wiper or anti-fouling guard selected

SUNA.x1xxx

Integrated bio-fouling wiper

Mechanical wiper integrated into the instrument housing, mechanically cleans optical window prior to each sample, best available bio-fouling protection
