Guided by serving the scientific and technological development of the country, provinces, and cities,
as well as the demand for modern marine and environmental protection industries
The instrument is specialized in the measurement of COD in seawater. According to the national standard of sea water (GB17378.4)the measurement of COD is performed by the sequence of alkalinepotassium permanganate oxidation, potassium iodide reduction andspectrophotometry. lt can be integrated into buoys, shorebasestations, survey ships and other platforms. It is suitable formeasurements of dilute samples in the ocean and concentratedsamples in the discharge outlets.
High Precision Submarine pH Analyzer
High precision submarine pH analyzer is a kind of in-situ sensor basedon the principle of spectrophotometry, which has the characteristics oflow power consumption, high precision and good accuracy. It is small insize and easy to be integrated to monitoring platforms such as buoys,shore stations and survey ships. lt is suitable for marine environmentalinvestigation and monitoring, and it can also provide measurement datafor scientific research requiring high precision pH such as ocean acidifi-cation and carbon cycle investigation.
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.
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.
