Long neck thermometer question - how far in does it need to be?

[rockgardenlove]

Hey,
I've got my long-neck thermometer inserted through the lid of my pot, This means only the bottom 2 & 1/2" are actually in my heating mashwater.

Will this give me accurate readings? Not quite sure.
Thanks!

It won't while you are heating it, but once you stir it up it will. I suggest that you stop short of your target temp, stir and then take a reading. Even with the thermometer positioned further down the water column I still have to do this myself. Not a big deal. Just stop heating 5 or 10 degrees below target and bump it up as neccessary. It's easier to add heat than it is to wait for it to cool.
