Curt, or anyone,

How do we know when the ORP probe needs to be replaced? Since we don't need to calibrate it, there's no way to see if it's starting to sway or jump like a pH probe...

I recommend that you replace the ORP probe at the same time as your pH probe. They have similar construction so they should age at about the same rate.
