SUNA V2 Nitrate Analyzer

产品描述

Technical indicators

Sea-bird Scientific SUNA V2 (Underwater UV Spectroscopy Nitrate Analyzer) is a UV Spectroscopy Nitrate Transfer Analyzer that does not use chemical reagents. It uses ISUS (In Situ Ultraviolet Spectroscopy) UV nitric acid developed by MBARI Research Institute The salt determination technology, with the help of the Satlantic technical team, revised the design and developed the second-generation UV spectroscopy in-situ analyzer SUNA V2, which is used for the raw of nitrate in the increasingly harsh field environment (high turbidity, high CDOM) Bit long-term monitoring.

Through the improved optical system and built-in intelligent sampling adjustment system, SUNA V2 can achieve accurate measurement of nitrate in various water bodies (from the blue ocean to stormy rivers and stream runoff), leading the industry in accuracy and stability.

SUNA V2 is a solution for nitrate online monitoring. The many optional features provided by SUNA V2 make it the most cost-effective choice for daily nitrate determination.

Application field

Used for long-term online monitoring and profile measurement of nitrate in the following water bodies.

Lakes and rivers

Coastal estuary

Drinking water storage

Agricultural irrigation system
