Overview
Product Advantages
Optical water sensor is an innovation technology which can detect water quality in real time in a sustainable way.
Product details
1
Full spectrum Detection
Full-spectrum sensors emit continuous light (e.g., 200-800nm via xenon lamp), capture absorption/reflection data across wavelengths, and decode parameters (COD, turbidity, heavy metals) via AI, surpassing single/dual-band limitations.
2
Auto-cleanning wiper
Built-in wiper (auto-cleaning hourly，can be customized) prevents bubble/contaminant interference. Wiper lasts ~6 months in clean water. Includes spare wiper for easy replacement, ensuring long-term accuracy.
3
316 steel material +IP68 protection
Withstands 6bar pressure (60m underwater depth). Dustproof & corrosion-resistant for reliable monitoring in harsh water environments.
4
Built-in 6m Cable
6m waterproof cable for most deployment needs. Longer extension cables are available for extended range. Durable construction ensures stable signal transmission, making installation easy in various monitoring scenarios!
5
Easy connection
Standard RS485 communication with Modbus RTU protocol for simple wiring. Offers strong anti-interference and stable transmission, enabling easy integration with monitoring systems for efficient installation.
6
Well packed
Our water quality sensor comes with custom-fit foam protection in the packaging, ensuring shock absorption and damage prevention during shipping and handling. Reliable delivery guaranteed!

Detection theory
Different organic matter has specical absorption spectrum in the UV region
Water’s fingerprint
This multi-parameter water quality sensor simultaneously monitors COD,BOD,TUR,Temperature etc., creating unique "water quality fingerprint" models.
The system generates 3D water quality distribution maps for environmental enforcement and hydrological research. Integrated AI learns regional water patterns, achieving >95% pollution identification accuracy.
By matching real-time data with fingerprint databases, it pinpoints pollution sources (e.g., factory discharges) .
The system generates 3D water quality distribution maps for environmental enforcement and hydrological research.
