InfThermometers and Accurate Room Temperature
I am trying to get an accurate read on the room temperature in my main level. The 3 'standard' thermometers I own (2 Honeywell, 1 Genera-Brand) all say the temperature is 81F. However, when two HVAC salesmen brought over their 'Gun Style' infrared thermometer, pointing it at the main level walls/kitchen surfaces registered the room temperature as 70F (at the same time as the other 3 thermometers say 81F). Given that I'm sweatin' on the main level (the outdoor temperature was approx 87F at the time), I'm inclined to believe 81F is the 'real' room temperature, but the salesmen claim the infrared is 100% accurate and the room temperature is in fact 70F. Can anyone confirm/deny which measurement is more reliable?
