Digital Water Quality Blue-Green Algae Density Sensor
>>Overview
The Blue-Green Algae Sensor utilizes the characteristic absorption and emission peaks of cyanobacteria in the spectrum. It emits specific wavelengths of monochromatic light into water, which is absorbed by cyanobacteria. The cyanobacteria then release another wavelength of monochromatic light, and the intensity of this emitted light is proportional to the concentration of cyanobacteria in the water.
Applications Include:
- Microalgae Monitoring: Quantifying microalgae populations in marine bays and harbors
- Freshwater Analysis: Detecting green algae and cyanobacteria in rivers, lakes, and reservoirs
- Aquaculture Management: Monitoring red algae levels in mariculture facilities
- Cultivation Control: Measuring green algae concentrations in bioreactor processing systems
>>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 blue-Green Algae Sensor ensures accurate and stable signal transmission.
