Maintenance schedule

Unlike the electrochemically-dissolved oxygen probe technology, the fluori-dissolved oxygen probe does not consume oxygen and does not require frequent cleaning (except when applied to viscous liquids).

Maintenance tasks	Recommended maintenance frequency
Cleaning sensor	Clean every 30 days
Check sensor and fluorescent cap for damage	Check every 30 days
Replace the fluorescent cap	Change once a year
Calibrate the sensor (if required by the competent authority)	According to the maintenance schedule required by the competent authority

Note:

The maintenance frequency in the above table is only a recommendation. Please maintain the sensor according to the actual usage of the sensor. However, the replacement of the fluorescent cap is recommended to be replaced once a year.
