pH Probe

[TheEngineer]

I have a pH probe that's been sitting dry for probably a few years at this point. Is it salvageable or should I just toss it and buy a new one?

It is likely dead, but soak it for a few days in diluted seawater and then if you can calibrate it and get it to read the calibration fluids correctly, it is good to go.

OK, cool. I'll give that a shot.

Just to close the loop on this.... I let the probe sit in my tank for a few weeks and saw that it was showing some fluctuations in pH and was in the general ballpark of my tests. I tried to calibrate it today and voila! It works! Who woulda thunk it?
