You are likely right one is very possibly correct and the other is a degree or two different.
Or one is a degree or two high and the other is 3 or 4 degrees high. That is my point, with out one thing that is accurate you have no idea. I always assume that any unit is at the extreme end of its variation and hope that is not the case. I then go to something that is known to be accurate. The average thermometer will be close but the law of averages is font use the highest and lowest with a sample of two you have...

I have a very high standard one degree I can tolerate two? No way. If I have two units two degrees apart I pull both and set them aside for checking. If a unit is more than one degree from correct it is gone. That is my standard one degree no more. On this forum some accept 6 degrees off of correct. I can't , my issue but my advise and suggestions are based my experiences and therefore my issues. You need to decide what you can live with. I can just explain what I believe and what leads me there.
