I want to insert a temp probe into my 100qt Extreme cooler through the outside wall. My question is how much of the probe needs to be in the mash to give acurate readings. I have a Blichmann Brew Mometer with a 5" stem and wondered if it would give me acurate mash temp readings. By the time I run it through the wall and fittings I'm probably looking at 2" of the probe being in the mash. Would I be better to buy the 12" stem thermometers and using a compression fitting? Can you get a compression fitting small enough to go on the small stem probes? I want to put it through the outside to keep from opening the cooler to take temp readings.
