Fluorescence chlorophyll sensor DCH-800A

Product Overview
The chlorophyll sensor uses the characteristic that chlorophyll A has absorption peak and emission peak in the spectrum to emit monochromatic light of specific wavelength into the water, chlorophyll A in the water absorbs the energy of monochromatic light, releasing monochromatic light of emission peak of another wavelength. The light intensity emitted by chlorophyll A is proportional to the content of chlorophyll A in water. This product is widely used in the on-line monitoring of chlorophyll imported from waterworks, drinking water source and aquaculture, as well as the on-line monitoring of chlorophyll in different water bodies such as surface water and landscape water.

Applications

• Online chlorophyll monitoring for waterworks inlets, drinking water sources, and aquaculture
• Chlorophyll monitoring of various water bodies: surface water, landscape water, and seawater
• Environmental monitoring for algae bloom prediction and indirect nutrient loading determination

Features

• Fluorescent pigment-based measurement, enabling early algae bloom prediction
• In-situ & rapid detection, no sample extraction/treatment required
• Compact, field-replaceable probe design for easy maintenance
• Digital sensor with strong anti-jamming capability and long transmission distance
• Standard digital signal output, supports integration/networking without a controller
• Plug-and-play, quick and convenient installation
• Suitable for long-term online and spot monitoring (including remote areas)
