Dissolved oxygen sensor is a device designed to measure the real-time dissolved oxygen content in water bodies and is an important tool for water quality monitoring. The core part is composed of special membrane materials and electrochemical sensors, which can accurately detect the concentration of dissolved oxygen in water. This type of sensor can not only provide accurate data, but also monitor water quality changes in real time, providing scientific basis for environmental management and ecological protection.
Dissolved oxygen water quality sensors are mainly used to measure the content of dissolved oxygen in water bodies. Dissolved oxygen is an important indicator for maintaining the survival of aquatic organisms and the ecological balance of water bodies, therefore sensors play a crucial role in water quality monitoring and environmental protection.
There are two main types of working principles for dissolved oxygen sensors:
Membrane type: The water sample is isolated from the electrodes inside the sensor through a semi permeable membrane. Oxygen reacts with the reducing agent to generate a current signal, and the dissolved oxygen content is calculated based on the magnitude of the current signal.
Fluorescent type: utilizing the effect of oxygen on the fluorescence intensity of fluorescent dyes. Fluorescent dyes are fixed on the thin film inside the sensor. As the oxygen concentration increases, the fluorescence intensity decreases. The dissolved oxygen content is determined by measuring the change in fluorescence intensity.
Application field
Water quality monitoring and protection: Dissolved oxygen is a key indicator for measuring the self purification capacity of water bodies and the health of the ecological environment. By continuously monitoring the dissolved oxygen content, water pollution problems can be detected in a timely manner, providing scientific basis for environmental protection and pollution control.
Industrial production: Accurate control of dissolved oxygen concentration is important for optimizing production processes, improving product quality and efficiency in fields such as biological fermentation, wastewater treatment, and food and beverage production.
Aquaculture: Dissolved oxygen is a key factor affecting the growth and survival of aquatic organisms. By monitoring the dissolved oxygen content in aquaculture water in real-time, it can ensure that aquatic organisms are in a good growth environment and improve aquaculture efficiency.
Environmental Science Research: Used for the study and teaching experiments of aquatic ecosystems, helping students and researchers gain a deeper understanding of the importance of water quality monitoring and environmental protection.
