What are you guys using? There are a lot out there, and many are cheap and crap. I was using a mercury filled one for that, and my cooling temps, but cooling so rapidly seems to have messed it up. There are now spots of mercury all along the length of the tube that did not drop with the bulk of the mercury as the temp decreased.
Thoughts? I would like to use it for mash temps, and cooling temps.
