Product Description Product DescriptionThe digital dissolved oxygen sensor is an advanced measurement device designed to accurately determine the concentration of dissolved oxygen in water. Utilizing the fluorescence quenching method, this sensor provides precise and reliable measurements, making it an essential tool for a wide range of applications, including aquaculture, environmental monitoring, industrial water quality control, and research. This product specification aims to provide a comprehensive overview of the sensor's features, operating principles, applications, and technical specifications.Operating PrincipleThe digital dissolved oxygen sensor operates based on the fluorescence quenching principle. This method involves the use of a fluorescent material, which is excited by a light source, typically emitting red light. When oxygen molecules are present in the water, they interact with the fluorescent material, causing a reduction in the fluorescence intensity-a phenomenon known as fluorescence quenching. The time duration of the excited red light is inversely proportional to the concentration of oxygen molecules in the water. By measuring this time, the sensor calculates the oxygen concentration, providing a highly accurate and responsive measurement.
