How long do most people get out of a pH probe? I just replaced my PinPoint pH probe today the old one failed several months ago giving a raw reading of like 2000. I bought that one in 2016.

Annually wow! OK I'll have to pay attention more. I don't have anything like a macro set up to do something based on pH so it is not that critical that they work 100% of the time. But I will get a spare. When replacing the pH probe, it looks like my other probe is also toast. So I guess I need to order 2 more. Are you using the Pinpoint ones?
It depends on the quality of the probe and what its measuring. They should be calibrated every month or so and the hobby grade ones we get I would expect to last 1 yr to 2/2.5 yrs. Now if you use it for measuring kalk stirrer pH or something life expectancy will tend to drop because particulates can plug the holes in the probe and cause it to fail.
As a reference the ones I use in industrial applications are either Metler Toledo or Emmerson with an advertised lif expectance of 2-3 yrs last between 3-4 years with 2x per month cals.

Longest I have had one last is three+ years. They use to last me two years until I built a low flow probe holder that also blocks light. The less marine growth and less water passing the probe extended their lives by 50%.
