Optical DO sensor

The Optical Dissolved Oxygen (DO) Sensor is an advanced measurement device designed for accurate and reliable monitoring of dissolved oxygen levels in water. It operates on an optical luminescence principle, where oxygen concentration is determined by measuring changes in light emitted from a sensing layer.
Unlike traditional electrochemical sensors, optical DO sensors do not consume oxygen and require minimal maintenance, making them ideal for long-term continuous monitoring in demanding industrial and environmental applications.
