I got a Milwaukee pH56 last year for Christmas. I've had issues with it right from the start.
The first was that it took forever to calibrate and would drift. The pH readings were NEVER the same, even a minute apart. So, they sent me a new electrode. That one worked for a while, but about 5 months later it wouldn't calibrate. It read "wrng" whenever I placed it in the 4.01 buffer.
They offered to look at it, but told me a new electrode would be about $60. I am definitely not one to veto the experts, but I told the tech that this was the third electrode and so maybe it was a different issue? Well, they told me to send it in. They sent it back to me a week later, with no note. But I was assuming the electrode was replaced again.
I calibrated it about a week after I got it back, and it seemed fine. But about two weeks later I was having a brewday, and the meter would NOT calibrate. It says "wrng" when I placed it in the 4.01 buffer.
I knew the electrode was good, as I just got it back, so I spent $20 and bought new packages of buffer. I am trying to calibrate it today, and when I put it in the brand new 4.01 buffer, it reads "wrng". If I keep at it, it eventually does say "4.01 cal".
The electrode has never dried out, never been exposed to freezing or hot temperatures (room is 63 degrees), and I cleaned it today with the electrode cleaning solution, thinking that was the issue. It still is happening.
I'm an intelligent person, so it's not like I'm abusing this item and dropping it and expecting it to work. I've "babied" it, blotting only to wick up water when moving it, not exposing it to wort above 75 degrees, etc.
What the heck is going on? Is it possible to have such issues, and not have the problem be with the meter itself and NOT the electrode? It's more than a little frustrating, as it has worked correctly for maybe one month of the last year.
