Blue green algae sensor for water quality is a device to measure the concentration of blue-green algae in the water body; it adopts fluorescence principle, which is more efficient and quicker than the traditional manual counting method and can be monitored online in real time; the internal increase of filtering algorithms makes it resistant to external light interference; the built-in temperature transmitter can automatically compensate for the temperature. It can be used for research, investigation and detection of rivers, lakes, ponds, marine survey, aquaculture, drinking water sources, algae and phytoplankton conditions.

Tips: What is the measurement principle of this sensor?
The RS485 Blue Green Algae Sensor uses the fluorescence measurement principle. This method involves emitting light at a specific wavelength that excites the blue-green algae cells, causing them to fluoresce or emit light at a different wavelength. The sensor then detects this emitted light, which correlates to the concentration of blue-green algae cells in the water. This technique is highly sensitive and specific, allowing for accurate, real-time detection of algae concentrations without requiring chemical reagents. Fluorescence measurement is particularly effective in aquatic environments, as it minimizes interference and provides reliable data across various water conditions.
