It appears you have the same short thermometer I have. Is that the glow in the dark, $7 thermometer from Amazon? I also have a Walmart thermometer with a 12" stem. The good news is the short thermometer I have is accurate. The bad news is the reading on the wall is not worth much.
In my short time (seasoning run and then 2 cookings) I have learned there is a major difference between the center of the UDS reading and a reading near the wall. This discrepancy increases as the temperature increases. When my center reading is about 250, my wall reading is about 190. When my center reading is about 325, my wall reading is about 210. This discrepancy is a bit exaggerated with our wall thermometer because our's, I believe, is shorter than most other wall thermometers. Our's extends about 2" past the wall while many extend 4 to 5 inches in. My Walmart thermometer is 12" long.
Because of this I decided to try a heat dispersment plate. Right now I have a 10" aluminum pie pan just above my charcoal basket which is about 9" below my cooking grate. It reduces the discrepancy but only a small amount. Now when my center runs 250, my wall runs about 200 to 205. I need to increase the diameter of my 10" pie pan or raise it or some combination of both.
