Anyway, I decided to do a test to check the smoker internal temperature and the temp probe using a second Polder probe. There were a couple revelations. The smoker temp reading seemed to be reading higher than the Polder and the built in temp probe didn't give me a reading above 199. It just read "HI" when it hit 200. I have read all over the forums that I should look for boston butt to hit 190 to 205 before pulling them.
Should the SM025 temp probe stop reading at 199?
