Dome temp vs Grate temp

Doing two racks of baby backs using the Turbo method ... I'm using a Maverick E732 for monitor my temp, it says 350, my dome thermometer says 400 ... 50 degrees seems like quite a bit to be off.

Any thoughts?

    Dome thermometer needs calibration?

    That's a good question, I'll have to calibrate it after today's cook. Can I assume I just need to 'trust' my Maverick?

  • Trust the maverick. I've had the dome off by as much as 75 before
  • I am doing spare ribs STL style today. Set the PitMaster @ 230 with my pit probe on one of my AR's upper racks(same rack I'm cooking the ribs on). Dome thermometer has been reading about 215 degrees all day.

    Thank you, I've only had my BGE a short time, so I'm still just a bit shaky

    Calibrate and then trust your indications-and the dome will usually (key word) run around 20-40*F hotter than the cooking grid when you start off indirect.  The gap will close the longer the dome is shut.  50*F is not unusual...key is to have confidence in what you are measuring.  There are many thermal gradients within the BGE during a cook-FWIW.
