Product Features
①
Multi-Parameter Integrated Detection
Supports 21-parameter measurement, integrating Ion Selective Detection (23 ions optional, e.g., NH₄⁺, NO₃⁻, K⁺, Ca²⁺) and dissolved CO₂ detection based on the NDIR principle, enabling simultaneous capture of multiple critical water quality indicators to meet comprehensive monitoring needs.
②
Advanced Sensing Technology
The ion sensor adopts the ionic electrode method with a power isolation design for strong data stability; the CO₂ sensor is equipped with a patented optical cavity and dual-channel detector for spatial dual-path reference compensation. Both ensure high detection accuracy (Ion: ±5%F.S., CO₂: ≤±5%F.S.).
③
Easy Integration & Maintenance
Environmentally friendly design, easily integrable into existing water quality monitoring systems. The ion sensor supports direct immersion installation; the CO₂ sensor is equipped with a detachable protective cover and convection diffusion ventilation design to accelerate gas diffusion and facilitate daily maintenance.
④
Multiple Output Modes + Robust Structure
The ion sensor outputs via RS485 (MODBUS protocol); the CO₂ sensor supports multiple output methods such as UART, IIC, and analog voltage. Both are made of polymer plastics with a waterproof design, suitable for long-term use in multiple environments such as seawater and freshwater.
⑤
Flexible Calibration + User-Friendly Operation
The ion sensor supports custom standard solution calibration (forward/reverse curves); the CO₂ sensor has a manual calibration function (MCDL pin) for on-site zero adjustment, with user-friendly operation to lower the usage threshold.
⑥
Flexible Expansion + Plug-and-Play
In addition to the core parameters of ions and CO₂, other Luminsens series sensors can be freely expanded later without complex modification, achieving plug-and-play to adapt to the dynamic upgrade of monitoring needs.
Application
●
Aquaculture Industry (Seawater/Freshwater)
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.
●
Comprehensive Water Quality Monitoring Projects
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.
●
Industrial Water Treatment & Environmental Quality Control
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.
●
Food and Beverage Production Quality Control
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.
●
Scientific Research & Ecological Environment Monitoring Projects
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.
