Only had time this morning to do some temp measurements at 235* setting (I don’t plan on smoking past this temp on a regular basis…I might even smoke around 200ish, but it seems like many folks smoke somewhere between 225-250* and 235 seemed like a good mid-point for me to measure).
Ambient info: 73*, started setting up around 7:15a, Central Florida, windy morning (all directions, could not position for least wind impact), sunny
Controller set to 235* - took about 10 minutes to stabilize per the controller display
Heat shield slats were closed for smoking/indirect cooking
Probes: iVation wireless (1 grill probe and 1 meat probe); meat thermometer that came with the grill
Baseline info:
I heated a cup of water for 2 minutes in the microwave, set all three probes, PLUS a Weber instant read meat thermometer for additional variance info.
My only issue doing this is that I don’t know how accurate meat probes are after a certain temp since they are made to measure internal meat temp, and the window for temp error might increase with temps, but oh well! (See pics below)
Edited for formatting:
Between the Weber thermometer and the grill’s meat probe, there was a 2* difference (Weber displays higher temp).
Between the iVation meat probe and the grill’s meat probe, there was a 6 degree temp difference (iVation higher temp).
Between the iVation grill probe and the grill’s meat probe, there was an 8* difference (iVation probe reads the higher temp).
Between the iVation probes themselves, there was a 3* difference in readings (grill probe was higher temp reading).
Important: Throughout the readings, I saw the grill temps fluctuating from 230*-304* (per the iVation grill probe in the very center/center position…note that I did not sit and watch the temps the whole time, this is just what I caught on occasion).
Temp was constantly moving up and down, never staying at one temp for more than a few seconds (less than 5 seconds). I believe the grill’s controller is programmed to take the average temps over some time (X number of seconds) based on some area around the center of the grill and drop pellets and adjust fan speed based on this formula.
I took temps in three positions (center, then back, then front) all over the drip pan/heat shield as best as I could visually line up; see pics below):
Left probe: iVation Meat probe
Center: iVation grill probe
Right: Smoke-n-Hot grills meat probe plugged into the controller
Here’s what I captured (keep in mind, these temps were recorded as unit was either heating up or just starting on its way down after it was determining what was needed to keep an average of 235* and I was more concerned with variance from left to right at this point).
Also, I will account for the variance between the iVation probes and the grill’s meat probe by decreasing by the amounts indicated above (6 degree decrease for the iVation meat probe and 8 degree decrease for iVation meat probe):
Center (L/C/R temps):
258*/285*/265*
Back (L/C/R):
246/263/262
Front (L/C/R):
249/263/262
