【Product Description】

The Oil-in-Water Online Sensor adopts UV fluorescence detection technology, offering high accuracy and sensitivity for real-time monitoring of trace oil pollutants in water. It features an RS485 interface with standard Modbus protocol, supporting fast response, automated operation, and data logging.


【Working Principle】

Utilizing UV fluorescence technology, the sensor quantifies oil concentration in water by measuring the fluorescence intensity emitted by petroleum hydrocarbons and conjugated double-bond compounds after absorbing ultraviolet light. Aromatic hydrocarbons in petroleum generate fluorescence under UV excitation, and the oil content in water is calculated based on the fluorescence intensity.

【Application】

Environmental Surface Water, Municipal Wastewater, Industrial Wastewater

【Features】

Reagent-free measurement ensures zero pollution, offering a more economical and eco-friendly solution
Equipped with a self-cleaning brush to eliminate oil residues and maintain measurement accuracy
Optical and electronic filtering technologies minimize ambient light interference, ensuring reliable monitoring
Corrosion-resistant housing with IP68 waterproof rating, RS485 communication interface, and standard Modbus protocol for easy integration
