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.
