Chlorophyll sensor

Fiber optic 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.

Features：

1. Digital sensor, RS-485 output, support MODBUS

2. Automatic cleaning brush to prevent contamination and eliminate air bubbles

3. Direct measurement, simpler than traditional analysis methods

4. Continuous online monitoring, real-time control of water quality dynamics
