I ended up using dish soap, but I must have used too much because the tubing kept sliding around after I'd slid it on (went on really really easily, too). So I had to tie a knot at the top of the tubing, with the cable inside, to keep it from sliding around any more.

Seems to be working fine with the dish soap in there, so I'm not too worried. Getting those o-rings on it was very tough, and I doubt it's really water tight, but I really just want it to be safe in case it slips into some liquid and I grab it immediately. Not going to soak this thing at all (I'd probably get some dish soap out if I did).

my attempt to put the silicone tubing from the pet store did not go smoothly at first, but then I accidentally pulled the cord out of the probe and just put the tubing on. I then pushed the cord back in the probe and tested it in boiling water and it seemed to work just fine.

I used the flexible rubbery tubing (it might be called surgical tubing) instead of the clear vinyl stuff.

I just used my "wort proofed" probe this weekend and it worked like a charm. Submerged in the mash and all. I used #68 o-rings (couldn't find 70 in three different stores). With one under the tubing and two over I don't see much of anything getting int here. Good work Bobby!

so when you do this wort proofing, can you just leave it in the wort during the boil, or do you have to take your reading and take it out?

I left mine in without doing that and now it reads 123 degrees at room temperature. Will the baking idea fix this or is this one shot

Baking fixed mine, but all I had in mine was sanitizer solution. Not sure if the sugars in Wort would continue to affect the thermoprobe afterwards, but I doubt they'd make any real difference.

Couldn't tell if you'd already wort-proofed your probe from your post, but if so, you may not want to leave the tube on there when you bake it.

I don't see a point in reading a boiling temp (boiling happens at 212). I use the thermometer for mash temps.

And yes, the baking idea should fix. I had the same issue before wort proofing and it worked like a charm.

I don't know many people who can claim they've completely submerged the probe and wire without having a "misfire" reading afterwards. I'm pretty sure it's a moisture thing that messes with the thermocouple reading. If you're going to put this probe in liquid often, you really should waterproof it as I outlined.

cool! thanks. I did it for an extract batch and left it in while i was steeping at 153 and then i turned it up to 170 for a quick dunk for a BS partial mash.

Thanks for the help!

I just thought they were already waterproof.. so much for that idea
