In-situ On-line Five Nutrient Monitoring Nutritive Salt Analyzer
The nutritive salt analyzer is our key research and development project achievement, developed by Frankstar. The instrument completely simulates manual operation, and only one instrument can simultaneously complete the in-situ on-line monitoring of five kinds of nutritive salt (No2-N nitrite, NO3-N nitrate, PO4-P phosphate, NH4-N ammonia nitrogen, SiO3-Si silicate) with high quality. Equipped with a handheld terminal, simplified setting process, and convenient operation. It can be deployed on the buoy, ship and other platforms.

Mobile Shipborne Water Quality Monitoring System
Frankstar shipborne water quality monitoring system is a fully integrated, autonomous shipborne system for continuous marine water quality monitoring. Combining multi-parameter sensors with high-sensitivity nutrient analyzers based on proven wet-chemistry methods, it delivers laboratory-grade data in real ocean conditions.
Intelligent control, based on GNSS/BeiDou positioning and vessel speed enables adaptive sampling during navigation. Fully autonomous and operator-assisted modes, together with automated calibration and maintenance, ensure long-term stability, reliability, and low operational workload.
Designed for unattended operation, the system supports continuous data acquisition, storage, and transmission, providing high-quality datasets for oceanographic research, environmental monitoring, and smart ocean observing networks.

In-Situ Nutrient Sensor
Frankstar in-situ nutrient sensor adapts established wet-chemistry methods into a fully automated, in-situ nutrient analyzer. The instrument strictly follows national standard detection protocols and accurately replicates manual laboratory procedures. Using precise reagent handling and automated reaction control, a single In-Situ Nutrient Sensor can simultaneously and continuously measure up to five key nutrients: nitrite (NO₂-N), nitrate (NO₃-N), phosphate (PO₄-P), ammonia nitrogen (NH₄-N), and silicate (SiO₃-Si).
