Art.No.: DW030402
Keywords: Nutrient Analyzer
Supplier: Qingdao Watertools Technology Co., Ltd.
The in-situ nutrient analyzer is a chemical analyzer suitable for shallow water areas. Dissolved nutrients including ammonia (NH3-N), nitrite (NO2-N), nitrate (NO3-N), phosphate (PO4-P) and silicate (SiO2-Si) can be measured. It is small in size, easy to carry and apply to install on buoys, shore stations, survey ships and other monitoring platforms. It is suitable for ocean, estuary, river, lake and other aquatic environments. It provides high-precision, continuous and stable data for eutrophication research, phytoplankton growth research and environmental change monitoring.
Features
l Equipped with a prefilter for high-turbidity water
l Modular designing for convenient equipment installation and maintenance
l Automatic light-source correction improving the measurement reliability
l Waste liquid recovery device to avoid pollution
l Data storage and backup function; expandable range
Application
It can be applied to various monitoring platforms such as buoys, shore stations, and shipboards, and has a long maintenance-free period. Complete indoor performance test, pilot test, environmental routine and marine application demonstration.
