What are the advantages of optical type dissolved oxygen sensor?

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


Higher initial acquisition cost Slower measurement response time than traditional electrochemical sensors Higher power consumption than traditional electrochemical sensor
