Product Introduction:
The is-3N1P type in-situ water quality nutrient analyzer features a low-power design, making it suitable for in-situ submersible online monitoring, particularly in applications powered by solar energy, such as buoys. It can continuously monitor parameters like ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, and phosphate on the same device. The analyzer is compatible with and can be expanded to include other parameters such as silicate, total phosphorus, total nitrogen, and COD. It consists of a new detection system, data processing system, and embedded software. The instrument can be remotely controlled and operated via software. It is applicable for the determination of nutrients in seawater, surface water, and groundwater.
