Advantages in Marine and Freshwater Systems--Fast Response Time, Long-Term Signal Stability, Lack of Oxygen Consumption, Immunity to Electromagnetic Noise or Interference

Fiber-optic oxygen sensors, commonly called optrodes or optodes represent a new technique for monitoring dissolved oxygen concentrations in marine and freshwater systems. The advantages of these sensors over traditional amperometric electrodes are their fast response time (< 1 second), long-term signal stability, lack of oxygen consumption, and immunity to electromagnetic noise or interference caused by changes in pH, ...
