If that is ok for you that is great. I am glad you have a solution. Personally the thought that the thermometer and thermostat can be wrong by 4º in either direction and the IR gun are (almost always) spec'd at +/- 2ºF some are worse. (did you check you guns specs? You should) would make me very nervous.
You are correct it's +/- 2. What I did was took my thermometer out and let it sit at room temp then gunned right where the probe was and it was right on, a couple shots I got were +\- 1 but I'm fine with that. I'm gonna take out my water bowel and check humidity- thanks for the help
