CHL351 Digital Fluorescence Chlorophyll Sensor with 0-500 μg/L Range and RS485 MODBUS for Water Quality Monitoring
The CHL351 Digital Fluorescence Chlorophyll Sensor provides accurate online continuous monitoring of chlorophyll levels in various water bodies using advanced fluorescence measurement technology.
This sensor utilizes fluorescence methodology to detect chlorophyll a concentration. A high-energy LED light source excites chlorophyll a molecules in water, producing specific wavelength fluorescence that is measured to determine concentration levels with exceptional accuracy.
Integrated brush prevents contamination and eliminates air bubbles for consistent performance
RS-485 output with MODBUS protocol support for seamless integration
Real-time water quality tracking with long-term stability and minimal maintenance
Superior repeatability and stability, unaffected by ambient light conditions

Chlorophyll monitoring serves as a direct indicator of phytoplankton growth and algal bloom conditions. High chlorophyll levels often correlate with elevated nutrient concentrations (phosphorus and nitrogen), which can signal pollution from anthropogenic sources and potentially lead to oxygen depletion and fish mortality events.
