It uses optical fiber structure, with excellent repeatability and stability, and no interference by external light. It is equipped with automatic cleaning brush to eliminate air bubbles and reduce the impact of contamination on the measurement, which realizes longer maintenance cycle. And it can maintain excellent stability for long-term online monitoring. The sensor adopts the principle of fluorescence method. According to the spectral absorption characteristics of chlorophyll a, it irradiates the water with high-energy LED light, excites the chlorophyll a to produce fluorescence of a specific wavelength, and then measures the concentration of chlorophyll a in the water.
