Product Description

RS485 Self-cleaning Chlorophyll Sensor Probe For Water Digital Chlorophyll Probe


A chlorophyll sensor is a device that is specifically designed to measure the concentration of chlorophyll in a sample. Chlorophyll is a pigment found in plants, algae, and cyanobacteria that plays a crucial role in photosynthesis. By measuring the concentration of chlorophyll, scientists can gain insights into the health and productivity of photosynthetic organisms, as well as the overall environmental conditions. Chlorophyll sensors are widely used in various fields, including environmental monitoring, oceanography, limnology, agriculture, and aquaculture, to assess the productivity, health, and composition of photosynthetic organisms in different ecosystems.




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.

Dissolved Oxygen Sensor: Measures the concentration of dissolved oxygen in water, which is important for assessing water quality and the health of aquatic ecosystems.


pH Sensor: Measures the acidity or alkalinity of a solution, providing information about water's chemical balance.


ORP (Oxidation-Reduction Potential) Sensor: Measures the tendency of a solution to gain or lose electrons, which is an indicator of its ability to oxidize or reduce other substances.


Turbidity Sensor: Measures the clarity and amount of suspended particles in water, indicating the presence of sediment, pollutants, or other substances.


Conductivity Sensor: Measures the ability of water to conduct electrical current, which reflects its ion concentration and can indicate the presence of dissolved solids or pollutants.


COD (Chemical Oxygen Demand) Sensor: Measures the amount of oxygen required to chemically decompose organic matter in water, indicating the level of pollution or organic contaminants.


Ammonia Nitrogen Sensor: Measures the concentration of ammonia and nitrogen compounds in water, providing insights into the level of nutrient pollution or wastewater contamination.


Sludge Concentration Sensor: Measures the concentration of sludge or suspended solids in wastewater treatment or industrial processes, helping to optimize treatment efficiency.


Blue-green Algae Sensor: Detects and monitors the presence of blue-green algae (cyanobacteria) in water bodies, which can indicate harmful algal blooms and potential health risks.


Oil in Water Sensor: Measures the concentration of oil or hydrocarbons in water, important for monitoring oil spills, industrial discharges, or other sources of contamination.


Nitrate Sensor: Measures the concentration of nitrates in water, which can indicate agricultural runoff, wastewater pollution, or other sources of nutrient enrichment.


Multi-parameter Water Quality Sensor: Combines multiple measurements, such as temperature, pH, dissolved oxygen, conductivity, etc., into a single device, providing a comprehensive assessment of water quality.
