I'm sure this has been done before, but I've never done it myself and thought I'd share what I found. I usually hang the Maverick ET-7probe that I'm using to measure the cooking chamber in the exhaust vent so that it's just kind if hanging in there. Tonight I smoked two small pork tenderloins and I set a block of wood with the probe inserted through a hole I drilled in it right in the center of the grate.
When they were done I took the probe that had been in the meat and hung it in the exhaust vent like I usually do. After about 10 minutes things had stabilized and I was surprised to see the one in the exhaust vent was reading 22 degrees higher than the one setting on the grate.
I let it go for a half hour and it stayed the same the whole time. I checked the thermometers before using them today and there was only 1 degree difference between them.
This was on the 18.5 WSM with the water pan removed. I assumed there would be a difference but I was surprised to see it was 20 degrees considering the water pan wasn't there to deflect the heat.
Now I'm thinking about all of the cooks I've done with the probe hanging in the vent giving me a reading that was around 20 degrees higher than what it actually was at grate level.
Anybody else ever compared the temps at these two spots and had similar results?
