Ironwood Gen 2 temp stability.

I have used my Gen 2 Ironwood numerous times and have never been concerned about temperature variation or attaining the correct temperature. Conversely there is plenty of anecdotal information from people who are concerned about temperature accuracy and precision. Note Traeger say that on a typical, good-weather day, your grill should fluctuate no more than ±15°F (±9.5°C) and I think that is a reasonable claim.

Out of interest and no doubt others have done a similar thing I set up an Inkbird system used with my Pro 575 by running the wired ambient probe through the vent in the rear of the grill and fixing it to within an inch of the Traeger built in probe and set up the display where I could monitor both, see below.

So far I have only monitored lower temperatures (< 120C / 250F) and at no point across this range has the variation between the 2 probes been greater than 5C / 10.5F during ignition and typically during cooking the difference is no more than as per the picture. (note temp is in C) Historically I have checked the Inkbird calibration at 0C / 32F and 100C / 212F.

Next step in to change the primary grill temperature to F and compare across the whole range up to 500F to see if are their any discrepancies but to date I have been impressed.

Even with the older generation Ironwood that I have, the temperature accuracy appears to be no more than 10 F at low temperatures. However, if I set the controller to 450F, I only get a chamber temp of 400F, a 40F difference. It will be interesting to see what you get on Gen2 at higher temperatures.
