Fiber-Optic Sensors for Measuring Oxygen Dissolved in Water

Fiber-optic sensors for measuring concentrations of oxygen dissolved in water are undergoing development. In comparison with electrochemical dissolved-oxygen sensors, the fiber-optic sensors are expected to be easier to use and maintain. Also, unlike electrochemical dissolved-oxygen sensors, the fiber-optic dissolved-oxygen sensors are amendable to connection into networks for taking measurements at multiple sites.
