A Dissolved Oxygen Measurement Based on Fiber Optical Oxygen Sensor

Abstract

For the determination of dissolved oxygen, working principle of the fiber optic oxygen sensor is studied. The sensor system calibration method and temperature compensation measures and their maintenance methods are analyzed. The dissolved oxygen sensors current widely using oxygen electrode and optical fiber oxygen sensor are compared. Optical fiber probe sensor is used in the current system, the multiple points and multiple samples can achieve the simultaneous detection.
