Advantages of Optical Dissolved Oxygen Sensor
Instant on-No warm up time is required
Exhibit very little calibration drift and can hold a calibration for months
Not susceptible to interference like hydrogen sulfide
Non consumptive method-no need to stir or provide sample movement
Less maintenance than traditional electrochemical sensors
Disadvantages
Higher initial acquisition cost Slower measurement response time than traditional electrochemical sensors Higher power consumption than traditional electrochemical sensor
