Default Traeger 075 Grill Thermal Survey

I got bored smoking some chuckies so I decided to do a "thermal survey" of my Traeger 075 grill (a surprise gift from my wife...especially so given that I have an FEC100).

Temp probes (I bought 30-each for $20 and found 12 that were within <2% tollerance):



On average, the rank order from the coldest-to-the-hotest grill spots:



Thermal survey at variying temperatures:



The raw data graph:



...and the dome temp graph:



Conclusion, the grill is hotter toward the rear and more so to the rear right.

...I know, where's the qview?

Wow... interesting stuff.. surprized the hot spots were so varied.

most amazed that you spent that much on thermometers

You didn't happen to do a gage repeatability and reliability study on those thermometers did you? You must be an engineer.

That is really cool and overall excellent work. I have always seen the outer edges of my Traeger get hotter than the middle but I figured with the fan blowing things would even out.

Thanks for doing this. I did this with my WSM to see where the hot spots were. I am currently looking at getting a Traeger and the temp differences was a concern.After checking the WSM seeing the edges hot because of air flow was expected. Did you try it without the aluminum foil. I found if not fitted tight to the pans of the WSM it changed the airflow and temps.

No. I will always use it with foil (shinny-side down), so I did it as it will be used. The foil, although heavy duty, is wrapped/conformed tightly to the drip-pan's contours so not to impede with the intended airflow (especially at the arched end).

...I do not think the cheap meat cares about inconsequential thermal variances:
