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
