Product Description

Online Continuous Blue Green Algae Sensor Analysis for Water Quality Monitoring


Features of blue-green algae sensors


Blue-green algae sensors often incorporate fluorometers, which use fluorescence to measure the concentration of blue-green algae. Fluorometers emit light at a specific wavelength, and when blue-green algae are present, they emit fluorescence that can be detected and quantified. This allows for accurate and sensitive measurements of algal biomass.


Multiple Wavelengths:
Some blue-green algae sensors use multiple wavelengths to analyze the composition of the water and distinguish between different types of algae. By analyzing the absorption and reflection of light at different wavelengths, these sensors can provide detailed and specific information about blue-green algae.


Remote Sensing Capabilities:
Blue-green algae sensors can be equipped with remote sensing capabilities, allowing for monitoring over a large area. This can be done using satellite imagery or other remote sensing technologies, enabling the detection of blue-green algae blooms in vast water bodies such as lakes or reservoirs.


Data Logging and Wireless Transmission:
Blue-green algae sensors often have data logging capabilities, allowing them to store measurements over time. They can also transmit data wirelessly, enabling real-time monitoring and remote access to the information. This feature ensures that the data collected is readily available for analysis and decision-making.


Integration with Water Monitoring Systems:
Blue-green algae sensors can be integrated into existing water monitoring systems or networks. This integration allows for seamless data collection, sharing, and analysis, providing a comprehensive understanding of the water quality and minimizing the effort required for monitoring.


Autonomous Operation:
Many blue-green algae sensors are designed for autonomous operation, meaning they can be deployed and left unattended for extended periods. This reduces the need for frequent human intervention, making them suitable for long-term monitoring applications.


Robust and Durable Construction:
Blue-green algae sensors are typically built to withstand harsh environmental conditions, such as immersion in water, varying temperatures, and exposure to sunlight. They are often made with corrosion-resistant materials to ensure long-term reliability and durability in the field.



The online blue-green algae sensor uses the principle of fluorescence method, which is more efficient and faster than the traditional manual counting method and can be monitored in real-time online. The sensor has better repeatability and stability. With an automatic cleaning brush, it can eliminate air bubbles and reduce the impact of contamination on the measurement, make the maintenance cycle longer, and maintain excellent stability for long-term online use It can play an early warning role on algae reproduction. A blue-green algae sensor is a specialized device used for the detection and monitoring of harmful algal blooms (HABs) caused by cyanobacteria. These sensors are designed to measure specific parameters related to blue-green algae, such as chlorophyll-a, phycocyanin, and phycobiliprotein fluorescence.
