6. Sensor Cleaning and Maintenance
Soak the lower half of the sensor in 100 mL inline sensor cleaning solution for 10-15 minutes. Gently rub
the sensor electrode head with the provided Q-tips. If the surface is not entirely clean, continue to soak the
sensor for an additional time until clean. Rinse the sensor with distilled water. Pyxis Lab Inline Sensor
Cleaning Solution can be purchased at our online Estore/Catalog at

Other Common Troubleshooting Issues
If the ST-765SS sensor output signal is not stable and fluctuates significantly, make an additional solution
ground connection–connect the black ground wire to a conductor that contacts the sample water
electrically such as a brass pipe adjacent to the ST-765SS.

Replacing pH and Oxidizer Electrode Head
The pH/oxidizer electrode head of ST-765SS Series can be replaced when the original electrode head
reaches its working life.
Order a replacement electrode head EH-765 (P/N 53061) from Pyxis and follow instructions as below.
1.
Turn off the sensor if it is powered on.
2.
Make sure there is no water on the sensor.
3.
Hold the ST-765SS main body with one hand and use the other hand to twist the stainless-steel
locking ring counter-clockwise until the front end of the black electrode is completely unscrewed,
as shown in

6.
To assemble the new electrode head, connect the plug, then insert the new electrode head into
the main sensor housing and ensure that the two protrusions on the electrode head are aligned
with the notches in the sensor main housing.
7.
Then twist the stainless-steel lock ring of ST-765SS in a clockwise direction until the threads of the
electrode head completely enter the ST-765SS housing as shown in
