【Product Description】

When a light beam irradiates liquid containing chlorophyll, the chlorophyll absorbs blue-violet and red light, emitting fluorescence in the red spectrum. The fluorescence intensity is directly proportional to chlorophyll concentration. The Chlorophyll-a Online Sensor employs fluorescence detection with digital intelligence, featuring automatic temperature compensation, calibration, data logging, analysis, and diagnostics. Equipped with RS485 output for seamless network integration, it is widely used in surface water monitoring and related industrie.

【Application】

Environmental surface water monitoring.

Aquaculture water quality management.

Emergency contamination detection.

【Product Features】

Self-cleaning function automatically removes optical window fouling and bubbles, enabling maintenance-free operation.

Optical and digital filtering technologies eliminate stray light interference for precise measurements.

IP68-rated corrosion-resistant housing for prolonged underwater deployment.

RS485 communication with Modbus protocol for system integration.
