Digital Water Quality Chlorophyll A Sensor
>>Overview
The chlorophyll sensor operates based on the characteristic absorption and emission peaks of chlorophyll A in the spectrum. It emits monochromatic light of a specific wavelength into the water. Chlorophyll A in the water absorbs the energy from this monochromatic light and re-emits monochromatic light of another wavelength. The light intensity emitted by chlorophyll A is directly proportional to the concentration of chlorophyll A in the water.
The chlorophyll sensor utilizes optical technology with an integrated design, offering high-efficiency power management, a robust structure, and stable performance. Maintenance-free and requiring no frequent calibration, it enables long-term online operation. This sensor is suitable for applications in rivers, lakes, ponds, marine surveys, aquaculture operations, drinking water sources, as well as research, monitoring, and analysis of algae and phytoplankton conditions.
>>Feature
- Fluorescence-based pigment measurement to identify potential water blooms before impacts occur.
- Rapid detection without extraction or additional processing, avoiding issues caused by stagnant water samples.
- Digital sensor with strong anti-interference capabilities and long-distance signal transmission.
- Standard digital signal output (RS485 Modbus RTU) enables integration and networking with other devices without a controller.
- Easy on-site installation and plug-and-play operation.
- Employs a light source method for fast response and stable signals.
- Stainless steel electrode housing withstands temperatures from 0 to 45°C.
- Specialized four-core shielded cable for chlorophyll A sensor ensures accurate and stable signal transmission.
