The NAS-2E in-situ nutrient analyzer: a device for the reliable measurement of nutrient concentrations in the aquatic environment

摘要

This paper describes the operational use of the NAS-2E in-situ nutrient analyzer. A very wide range on applications, programs and deployment scenarios are described. The NAS-2E is an in-situ wet chemical analyzer for remote deployment and the continuous automatic measurement of nutrient concentrations. The excellent reliability and track record of the device providing new in-sight into environmental conditions is discussed in detail.
