Nutrient In situ Analyzer

The nutrient in situ analyzer(ST5200) is a chemical sensor suitable for shallow waterareas. Water-dissolved five nutrients including ammonia nitrogen (NH3-N), nitrite(NO2-N), nitrate (NO3-N),phosphate (PO4-P) and silicate (SiO3-Si) can bemeasured. lt is small in size, easy to carry and place, and easy to install on buoys,shore stations, survey ships and other monitoring platforms. lt is suitable for ocean.estuary, rivers, lakes and other water bodies. lt provides high-precision, continuousand stable data for eutrophication research, phytoplankton growth research andenvironmental change monitoring.

TN/TP In situ Analyzer

The total nitrogen and total phosphorus in-situ analyzer is a wet chemical systemin-situ sensor for the determination of total nitrogen and total phosphorus contents inseawater. The sensor is designed on the basis of the principle of spectrophotometry.A sequential injection analysis technology is adopted to precisely control the amountsof different reagents and to ensure the accuracy and stability of data measured. Thesensor has the advantages of integration, low power consumption, high precision andso on, Long-term unmanned in-situ monitoring can be realized. Accurate, stable andreliable total nitrogen and total phosphorus measurement data can be obtained. lt canbe widely used in shore base stations, ships, buoys and other mobile/fixed platforms.

Integrated Marine Ecology Monitoring System

The integrated marine ecological integrated monitoring system is an online automatic monitoring system composed of a set of online automatic analysis instruments as the core, using modern sensor technology, automatic measurement technology, automatic control technology, computer application technology, and related special analysis software and communication network. The system can automatically complete the functions of water sample collection, data collection, data processing, GPRS/Beidou dual communication, etc., in addition to providing a variety of human-computer interaction interfaces, which can be customized according to the different needs of customers. The system has the monitoring function of the traditional fixed automatic water quality monitoring station, which can realize the automatic and real-time monitoring of dozens of seawater quality parameters including multiple parameters (temperature, salinity, turbidity, chlorophyll, pH, dissolved oxygen, oil in water, five-parameter nutrients (nitrate, ammonia nitrogen, nitrite, phosphate, silicate), total phosphorus and total nitrogen.

Surface Drift Buoy

The surface drift buoy is equipped with a 4G/Beidou dual-communi-cation and GPS/Beidou dual-mode positioning functions. Hangingstructures such as water sails and sensors can be customized.lt hasthe advantages of a small size, light weight, collision resistance.stable operation,reliable performance, and convenient customiza-tion. lt can be deployed to designated sites in oceans, rivers, lakesand other waters,with various vehicles such as aircrafts,shipsdrones and unmanned boats. lt is applied in the scenarios of emer-gencyresponse,environmental tracking and monitoring, targetsearch, etc.
