Reddit mentions: The best dial thermometers

Furthest thing from sexy but we use a 48" compost thermometer. Can grab temps anywhere we want in the tun. It's a tank (even after the glass face fell off) and works well. I do have to re-calibrate it every month or so but that's in the regular inspection cycle of our thermometers.

I'd much rather use a plain old clip on dial thermometer. It will stay on better, and is easier to read. Also, there's no risk at all of glass fragments and mercury in your beer if you break it mid boil.

I've thought about this for sometime because i want to build out a van so i can do ski touring, and theirs not always a shower available. Anyways, I've thought maybe a 5 gallon pot with a thermometer, being heated on a burner might work. I don't think it would take long to heat up considering that it only needs to be heated to 39C / 102F or so. You could at this point poor that into a pump sprayer, or use a portable shower head and put the pump right into the pot. As to how to do it in the van, i've thought maybe if you sat on a small bench in a portable plastic tub, or built your own wooden tub to your own dimensions. Then just either pour out the water, or pour into a greywater jug. If you built your own tub, you could even install a little drain into it with a rubber stopper.

Winters instruments has a spring mounted thermometer with a dual scale, and you can find them on Amazon.

I started with a 20 gallon Winware Aluminium kettle, a custom bag , ball valve, a clip on thermometer, and a couple of Aquatainers for no chill. I miss the simplicity of that setup.
