I'm brewing my first partial mash right now and I was wondering if a floating thermometer needs to be fully submerged in the water to give an accurate reading. I have about 2.60 gallons in a 10 gallon boiling pot so its not actually floating its resting more than anything. I was thinking if it's touching the bottom it could artificially increase the temperature. Would it be better to get a tall glass and fill it with water from the pot and float the thermometer in that instead?
