SUNA V2 and Deep SUNA Nitrate Sensors
Chemical-free UV absorption nitrate sensors based on MBARI-ISUS technology, for rivers through deep ocean; Deep SUNA rated to 2000 m for AUVs and gliders.
Description
The SUNA V2 measures nitrate in real time across a wide range of conditions, including turbid and high-CDOM waters, using the MBARI-ISUS UV absorption method. The Deep SUNA is redesigned for AUV and glider integration, with real-time temperature/salinity compensation, a corrosion-proof anodized aluminum housing rated to 2000 m, and in-field reference checks.
Key features
- Deep SUNA accuracy: ± 2 uM (±0.028 mg/l-N) or ± 10% of reading
- Deep SUNA power: 7.5 W (0.625 A at 12 V) nominal
