NAS-3X - The Original In-situ Nutrient Analyzer

The NAS-3X is the latest version of the leading in-situ nutrient analyzer for high-frequency time-series determination of nutrient concentrations in marine and fresh waters. Four versions are available for the measurement of nitrate phosphate, silicate and ammonia.

The NAS-3X is typically deployed unattended for periods of 1 to 3 months, although much longer deployments can be achieved. The NAS-3X has also been used near surface in many buoy and riverine applications or moored at depths down to 250m.
