The function of Fluorescence dissolved oxygen sensor is to measure the oxygen content in the water. The oxygen in the water will change with the pressure, temperature and salinity. The higher the pressure, the higher the dissolved oxygen, and the higher the temperature, the higher the salt. Generally, the oxygen in the water is air Infiltration into the water, it can also generate oxygen through the plants in the water, but many reasons in the water will consume oxygen, resulting in insufficient oxygen content in the water, so professional instruments are required to detect the dissolved oxygen content in the water.

Sensor maintenance
1) Sensor outer surface:
Clean the outer surface of the sensor with tap water. If there is still debris left, wipe it with a soft cloth. For some stubborn dirt, add some household washing liquid to the tap water to clean it.
2) The outer surface of the fluorescent cap:
Remove the protective cover at the front end of the sensor, rinse the dirt on the sensor window with clean water, and finally cover the cover; if you need to wipe, use a soft cloth and carefully wipe the force direction.
