They must be all be pretty similar. They don't really offer accuracy specs. Just a screw on the back.
Probably get one that goes into a thermowell so I can use it for a digital probe down the road.
Anyone ever use the Concord ones on ebay that swivel?
What I don't understand is what holds the thermomter into the thermowell? If I have a 0.5" threaded port, do I get a threaded thermometer, or does the thermowell thread in there. What holds the thermometer into the thermowell then?
Bobby M at brewhardware.com offers quite a few options. I believe he also has a good instructional video on kettle mounting that would help you out. He even has an option to kettle mount a digital CDN inexpensive thermometer.
All that said. I would just use a handheld digital stick like the CDN 450 for under 20 bucks and not bother with a kettle mounted thermo, but different strokes ....
Thanks, Just ordered my 3rd thermapen( they're so handy I keep misplacing them because they don't stay in one spot! ) and a backup RT600C. I like the thermomter Bobby sells, but the rt600c is more waterproof as it claims "dishwasher safe". I think its also faster by a second or 2. I had a horrendous brewday(s) this weekend because of a $8 thermometer acting up and wanna make sure that doesn't happen again...
I did look at Bobby's site, and noticed he has thermowells and dial thermomters. I just need a pair that will work together and that will fit into a 1/2" tee for my sightglass. I will go through all the videos at somepoint, nothing is jumping out at me atm. I guess I could just email him again. He got back to me pretty quickly about 1.5" silicon camlock gaskets.
Exactly why do you think you need a thermowell? A thermowell allows you to insert a probe into a liquid bulk and get an internal temperature, but it sounds like you are fitting this to a kettle where that doesn't matter
If you want to be able to swap out for a digital probe, brewhardware also sells a 1/2" NPT to probe fitting which you would swap out for the dial thermometer.
Just slide the probe in and out. I don't even put a wrench on the compression nut, just just good and finger tight and I can even pull the probe out a little while mashing so when I stir, I don't hit it.
