Chlorophyll Sensor Digital Fluorescence RS485 For Online Continuous Monitoring
Measuring Principle
Chlorophyll is essential to the existence of phytoplankton. Phytoplankton can be used as an indicator organism for the health of a particular body of water.
The CHL351 digital fluorescence chlorophyll sensor adopts the principle of the fluorescence method. According to the spectral absorption characteristics of chlorophyll a, the water is irradiated with a high-energy LED light source to excite chlorophyll a in the water to produce fluorescence of a specific wavelength. Then the concentration of chlorophyll a in the water is measured.
The chlorophyll probe adopts an optical fiber structure, which has excellent repeatability and stability and is not easily affected by ambient light.

Automatic cleaning brush to prevent contamination and eliminate air bubbles
Digital sensor, RS-485 output, support MODBUS
Direct measurement, more convenient than traditional analysis methods
Online continuous monitoring, real-time control of water quality dynamics
Longer maintenance cycle, maintain excellent stability when used online for a long time

About Chlorophyll
Monitoring chlorophyll levels is a direct way of tracking algal growth. Surface waters that have high chlorophyll conditions are typically high in nutrients, generally phosphorus and nitrogen. These nutrients cause the algae to grow or bloom. When algae populations bloom, then crash and die in response to changing environmental conditions, they deplete dissolved oxygen levels - a primary cause of most fish kills.
High levels of nitrogen and phosphorus can be indicators of pollution from man-made sources. Thus, chlorophyll measurement can be utilized as an indirect indicator of nutrient levels.
