Introduction to Optical DO Sensors
Optical Dissolved Oxygen (DO) sensors are advanced analytical instruments used to measure the amount of oxygen dissolved in a liquid, typically water. Unlike traditional electrochemical sensors, optical DO sensors are based on a principle of fluorescence quenching. When a light source excites a fluorescent indicator on the sensor’s surface, the emitted fluorescence is proportional to the partial pressure of dissolved oxygen in the surrounding medium. Optical DO Sensors
The advantages of optical DO sensors are numerous. They offer high accuracy and precision, long – term stability, and are less prone to interference from other substances in the water. They also have a faster response time and require less maintenance compared to electrochemical sensors. These sensors find wide applications in various fields such as environmental monitoring, aquaculture, wastewater treatment, and industrial process control.
