Chlorophyll sensor

The fiber-optic chlorophyll sensor adopts the principle of fluorescence method. According to the spectral absorption characteristics of chlorophyll a, it irradiates water with a high-energy LED light source to excite the chlorophyll a in the water to generate a specific wavelength of fluorescence and measure the concentration of chlorophyll a in water. The sensor uses a fiber-optic structure with excellent repeatability and stability, and is not easily affected by ambient light. Equipped with an automatic cleaning brush to 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.
