Both brew days if going by the installed thermometer my mash temp has dropped significantly over the hour. My strike temp was 160, I added my 26 lb of grains and after the first 10 mins it was still showing 160-162. That does not make sense. So then when I checked about 10 mins later it was down to 150. Well thats where I wanted to be. I checked 5 mins later and it said 140! First batch I ended up adding flame to it to bring it back up and then it was showing 160 again even though i flamed out at 150.
I did my first BIAB and found the same thing... it was accurate on ramp up and boil, but it showed a 10 degree drop over about 15 minutes. I think that on a mash since there is no fluid movement, the area around the TC port cools and gives false reading since a good 1-1.5" of temp probe is in the TC port. Initially I freaked, but grabbed a extra stainless thermowell and tossed my inkbird probe in there. It showed 149° and held for the hour (I blanket wrapped the kettle)
