500ug/L Online Digital Chlorophyll Sensor For Surface Water Monitoring

The chlorophyll sensor produced by Delfino is an online water quality sensor using RS485 signal output and standard Modbus protocol. The CHL351 chlorophyll sensor can be used with our digital controller. It uses the principle of fluorescence method. According to the spectral absorption characteristics of chlorophyll a, the water is illuminated by a high-energy LED light source to excite chlorophyll a in the water to produce fluorescence of a specific wavelength. Measure the concentration of chlorophyll a in the water.

Specification

Advantages

• The chlorophyll sensor adopts an optical fiber structure, which has excellent repeatability and stability, and is not easily affected by ambient light.

• With automatic cleaning brush to prevent contamination and eliminate air bubbles.

• Digital chlorophyll sensor, with RS485 output, supports Modbus communication protocol.

• Direct measurement, the measurement result is accurate and stable, simpler than traditional analysis method.

• It can be continuously monitored online, the protection level is IP68, and the water quality dynamics can be controlled in real time.

Applications

Suitable for monitoring the water quality of rivers, lakes, surface water, aquaculture waters, urban landscape rivers, and other watersheds.

About Chlorophyll

The content of chlorophyll a is one of the indicators to evaluate the eutrophication of water bodies. Chlorophyll is an important photosynthetic pigment for plant photosynthesis, which can be divided into four categories: a, b, c, and d.

Chlorophyll is insoluble in water, but soluble in organic solvents, such as ethanol, acetone, ether, chloroform, etc. Chlorophyll is very unstable and will be decomposed by light, acid, alkali, oxygen, and oxidants.

Chlorophyll a itself is not harmful to the environment, but it is an important indicator for estimating the biomass of phytoplankton. By measuring the content of phytoplankton chlorophyll a in the water, the primary productivity and eutrophication level of the water body can be grasped.
