Dome thermometer adjustable?

[JohnTak]

Can the Weber dome thermometers be calibrated and adjusted? I was just wondering because they have a huge range to cover with low and slow up to high temperature grilling. Mine seem reasonably close to my Smoke X at grate level temperatures.

I don’t think you can change how they work at all.
More accurate than the performer. When my smoke is half way through, in the middle of the bowl it seems to be the most accurate compared to my grill level probe. Last shoulder they were within 5 or so degrees.
