Maintenance

ORP Electrode and Cable
The most frequently replaced part is the ORP electrode, which will deteriorate with age. Refillable electrodes should be
checked for level frequently, and replenished with filling solution as necessary. An electrode may also fail because of:
• aging (slow response to changing ORP)
• coatings over the glass bulb (slow response to changing ORP)
• abrasion of the glass bulb (shift in calibration)
• chemical attack
• breakage
If you experience instability or lack of response, check the electrode, replace if necessary and recalibrate. Follow
manufacturer’s recommendation for cleaning the electrode. Take care not to damage input cables, or allow the connections
to get wet.
