Overview

AI-powered 235/254/275/550nm optics detect NH₃-N, COD/BOD/TOC & turbidity with higher accuracy than dual wavelength water sensor. 316 stainless steel & IP68 rating endure 60m depth. Auto-cleaning wiper resists fouling, while battery-powered operation enables off-grid deployment. Ideal for multiple water environment, such as wastewater plants, rivers, and industrial deep-water zones.

Product Advantages

Optical water sensor is an innovation technology which can detect water quality in real time in a sustainable way.

Environmental Friendly

No chemical reagent consume compared to tranditional detection.
Low electricity comsumptiion(6w/h).

Higher precision and accuracy

Specialized compastion of turbidity & Temperature, 1 nm spectral resolution ensure accuracy.

Less manpower involved

Data will be upload to the cloud server in real-time, reduced manual sampling time.
On-site calibration, less maintainance.

RoHS & CE certified

Global compliance and reliability

Product details

1

Dual-wavelength Detection

Measures at 254nm (organic compounds) and 550nm (turbidity), using turbidity data to calibrate organic detection for more accurate monitoring.

2

Mounting

Based on the water flow rate, we provide two kind of mouting choice.

Submersion Mount
(for flows <3m/s)

Full-immersion design with self-cleaning wwiper to effectively eliminate bubble interference. Compatible with 304 stainless steel mounting brackets, ideal for static water environments like reservoirs and wastewater treatment ponds.

Flow-through Mount
for flows>3m /s)

Flow reduction via diversion chamber/flow-through trough, to eliminate turbulent bubbles. Offers DN50-DN200 multi-size interfaces to accommodate various pipeline diameter requirements.

Meter transmeter

Two kind of meter transmeters, support the sensor working in different senario.

Wireless meter transmeter

Battery-powered • 180-day endurance • Real-time cloud sync • Designed for off-grid field use

Display meter transmeter

HD LCD screen • On-site operation • Stable wired power • Ideal for fixed monitoring

Detection theory

Different organic matter has specical absorption spectrum in the UV region

Ultraviolet absorption

Organnic matter absorb 275nm spectrum.
The absorption coeefciency differ from organic mater.

Intelligent algorithm

the sensor, paired with 254nm and 550nm light source, by utilzing the built-in intelligent algorithm to detect organic matter.

Water’s fingerprint

Water fingerprint modeling uses AI to analyze unique water characteristics, enabling precise pollution tracing and 3D water quality visualization
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.
