What are the advantages of Optical (fluorescence) dissolved oxygen measurement compared to the Polarographic and Galvanic methods?

Advantages of this method compared to those mentioned are: response time of less than 90sec compared to tens of minutes and even hours, shorter warm-up time, flow independency, long-term stability - stable measurements over a long period of time, dirt resistance and measurement independent, simple maintenance with easily replaceable oxygen exchange cap.
