For various aquaculture scenarios such as fish, shrimp, and shellfish, it monitors harmful ions (e.g., NH₄⁺, NO₃⁻), nutrient ions (e.g., K⁺, Ca²⁺), and dissolved CO₂ concentration in water bodies in real time, precisely regulating the water quality environment to ensure the healthy growth of aquatic organisms. Sensors can be expanded later as needed to adapt to the expansion of aquaculture scale or the addition of new monitoring parameters.
Applicable to various water bodies such as surface water, groundwater, domestic sewage, and industrial wastewater, it simultaneously detects ion composition (aiding pollution source tracing and water quality category determination) and dissolved CO₂ content (reflecting water body acid-base balance and ecological metabolic status), providing comprehensive data support for water quality compliance assessment and pollution control effect verification, and can be flexibly integrated into existing monitoring systems.
Suitable for water treatment scenarios in industries such as chemical, electronics, and food processing, as well as water quality monitoring in sewage treatment plants. It controls water salinity and pollutant ion content through ion sensors, monitors acid-base adjustment-related parameters during water treatment via CO₂ sensors, and supports the expansion of other functional sensors to build a customized water quality control system to ensure discharge compliance.
Focuses on the production process of carbonated beverages (e.g., Coke, Sprite, etc.), accurately measures the dissolved CO₂ content in products to ensure consistent carbonation taste and stable product quality; meanwhile, it can monitor the mineral ion content in beverages through ion sensors to assist in controlling formula compliance, adapting to the online monitoring needs of production lines.
Meets the needs of scenarios such as field research and marine/inland water ecological surveys, focusing on monitoring core ion and CO₂ parameters to support ecological environment change research. With plug-and-play expansion capability, other sensors can be flexibly added according to research directions, helping to ensure the completeness and flexibility of data collection.
