I would never put my probe in my wines, I always pull a sample. I have
a Hanna PHeP5 and there is no way you can clean that assembly well and
I would not want to risk damaging the probe either. I do 50ml samples;
it's not a big deal to me. I'm not saying things crawl out of my pH
meter, just that it's not something i would swirl in a glass of water i
was going to drink...

Are you sure it's even a good idea to sanitize a pH meter probe? They
are pretty delicate.
