Digital Sensor Fiber Optic Chlorophyll Sensor KWS-400 RS-485 Output
1. Applications
Chlorophyll and its metallic form are essential organic compounds located in chloroplasts, playing a critical role in capturing light energy and facilitating vital biological processes. Given their promising applications, the electrochemical properties of chlorophyll and metallic chlorophyll have garnered significant attention and research focus.
The fiber chlorophyll sensor operates based on the fluorescence principle. It employs a high-energy LED light source to illuminate water, taking into account the spectral absorption characteristics of chlorophyll a. This illumination stimulates chlorophyll a in the water to emit fluorescence at a specific wavelength, enabling the measurement of chlorophyll a concentration. The sensor's fiber structure exhibits outstanding repeatability and stability, remaining resilient against ambient light interference. Additionally, the integration of an automatic cleaning brush helps eliminate air bubbles, minimizing the impact of contamination on measurements. This design facilitates prolonged online use, extends maintenance intervals, and enhances overall measurement stability.
