Reagent-Free Measurement: Uses UV fluorescence method requiring no chemical reagents, reducing pollution and operational costs.
Turbidity Compensation: Dual light sources (254nm UV + 550nm IR) automatically compensate for optical path attenuation and turbidity.
Self-Cleaning Design: Features internal rotation cleaning brush for pipe self-cleaning and submersible self-cleaning capabilities.
Digital RS-485 Output: Supports Modbus RTU protocol for easy integration into existing monitoring systems.
IP68 Waterproof Rating: Fully protected against dust and long-term immersion in water, suitable for harsh environments.
Multi-Parameter Detection: Capable of measuring COD, TOC, and Temperature parameters simultaneously with high accuracy.
Custom Cable Length: Cable length is customizable, with 5m as the standard default option for flexible installation.
Compact & Portable: Small size (50mm diameter, 214mm length) allows for easy installation and online water quality monitoring.
