Portable Fluorescence Dissolved Oxygen Analyzer - China Suppliers and Factory for Real-Time Monitoring
❓ Frequently Asked Questions
🔹 What is a portable fluorescence DO sensor and how does it work?
A portable fluorescence dissolved oxygen (DO) sensor measures oxygen levels in water using optical fluorescence technology. A blue LED excites a fluorescent dye on the sensor cap; the intensity of the returning light is inversely proportional to the dissolved oxygen concentration, allowing accurate, drift-free readings without consuming oxygen.
🔹 What are the main advantages of fluorescence DO sensors over traditional electrochemical sensors?
Fluorescence DO sensors require no electrolyte replacement, have minimal maintenance, are not affected by flow rate, and offer longer service life. They also eliminate the need for polarization time and are less susceptible to interference from hydrogen sulfide and other contaminants.
🔹 Is this portable fluorescence DO sensor suitable for aquaculture applications?
Yes. The sensor is specifically designed for aquaculture environments, providing real-time dissolved oxygen monitoring in fish ponds, shrimp farms, and recirculating aquaculture systems (RAS). Accurate DO control is critical for maintaining healthy aquatic life and optimizing feed conversion rates.
🔹 How often does the sensor cap need to be replaced?
The fluorescent sensor cap typically lasts 1–2 years under normal operating conditions, depending on water quality and usage frequency. Regular inspection is recommended, and replacement caps are usually available as accessories to ensure continued measurement accuracy.
🔹 Can the portable DO sensor be used in both field and laboratory settings?
Absolutely. Its portable design makes it ideal for on-site field measurements in rivers, lakes, and aquaculture ponds, as well as for laboratory water quality analysis. The compact form factor and easy-to-read display ensure convenient operation in various environments.
🔹 What parameters does the fluorescence dissolved oxygen meter measure?
In addition to dissolved oxygen concentration (mg/L or %), the meter typically measures water temperature simultaneously, as temperature directly affects oxygen solubility. Some models may also provide salinity compensation to ensure accurate readings across different water types.
