Nexisense BGA-408-S Online Blue Green Algae Sensor Definition
The Nexisense BGA-408-S online blue-green algae sensor is a high-precision water quality monitoring device specifically designed for real-time measurement of cyanobacteria (also known as blue-green algae) concentrations in aquatic environments. This sensor is applicable in fisheries management, water pollution monitoring, and ecological research, providing scientific basis for public health and environmental protection.
Principle
The Nexisense BGA-408-S sensor utilizes the fluorescence measurement method. During the measurement process, the sensor emits monochromatic light of a specific wavelength into the water. When this light irradiates the cyanobacteria cells, the pigments within the cells absorb the light energy and re-emit light at a different wavelength. The sensor assesses the concentration of cyanobacteria in the water by measuring the intensity of the emitted light. This process is characterized by a fast response and high sensitivity, providing accurate concentration data in a short time.
