Do these exist? I’ve been reading up on the (in)accuracy of bimetal thermometers used in most kettles/mash tuns, and figured that–surely–there must be a digital, but expensive (of course!) digital thermometer option. Unfortunately, my searches can’t seem to turn up anything of the sort.
Just for the record, I do already own a Thermapen, a mercury thermometer, a Blichmann Brewmometer, and a couple other bimetal thermometers. I can use the Thermapen, sure, but I’d really like to just find a semi-permanent solution: something I can install and leave-be.

Interesting. How did you mount the readout? I like the idea of a $10 solution, though the $180 digital solution looks so freaking simple to install and use–it even looks like most kettle thermometers!
FWIW, I think I figured out what’s going on with my Blichmann Brewmometer. My gauge was accurate and fine, but I took it off (along with the ball valve) for cleaning. My OCD was getting the better of me, and I needed the thermometer to be visually perfectly aligned vertically, and so I twisted while holding the face. Well, observing closely, this has the same effect as turning the calibration screw! It was a “duh” moment.
I checked it against the thermopen, and it was within a degree or two 180F, 130F, and 70F. As good as it gets, I suppose.
I agree in principal. I would hope that all digital thermometers are using a thermoresistor; I have a hard time believing that would be intrinsically less accurate than a bimetal thermometer.

I used a nibbler to cut rectangular holes in the case of the water heater. Heater only had a 3vdc power supply, so I had to include an additional 12vdc supply.
