Online Fiber Optic Chlorophyll Sensor For Underwater Testing With Automatic Cleaning Brush
Description
The fiber-optic chlorophyll sensor adopts the principle of the fluorescence method. According to the spectral absorption characteristics of chlorophyll a, the water body is irradiated by a high-energy LED light source, and the chlorophyll a in the water body is excited to generate fluorescence of a specific wavelength, and the concentration of chlorophyll a in the water is measured. The sensor's fiber-optic structure provides excellent repeatability and stability and is less susceptible to ambient light. With automatic cleaning, the brush eliminates air bubbles, reduces the impact of contamination on the measurement, makes the maintenance cycle longer, and maintains excellent stability for long-term online use.

Feature
* Digital sensor, RS-485 output, support MODBUS.
* Automatic cleaning brush to prevent contamination and eliminate air bubbles
* Direct measurement is easier than traditional analysis methods
* Continuous online monitoring and real-time control of water quality
