How does a Ph probe die?

My Ph meter is acting strange. I calibrated it at 7 and 4. A couple of hours later when I was checking my mash Ph, the meter was reading 5.4 instead of the Bru'n Water prediction of 5.2.
My experience with Bru'n Water has been a very reliable predictor of Mash Ph.
So I ignored my meter, added the remaining acid BW predicted and went about my brewday.
After the brewday was over, I tested the 7 and 4 calibration solutions. They both read about .2 high.
Is the the normal way a Ph probe ends its life? When do you know when to replace your Ph probe?
