Digital Hygrometer Accuracy

[basil]

I have two new digital hygrometers (one from Don Salvatore, the other from Little Havana).
They are lying next to each other in my humidor and their vents are unobstructed. I've allowed them to equilibrate for 45 minutes. They read similar temps (within 0.1 degree), but one reads 66% humidity (Don Salvatore) and the other reads 77%. Even if you allow for a small inaccuracy, this seems to be too much a difference.
I thought these were supposed to be quite accurate (1-2%).

Now what? Do I need to buy a third to see which is right? Any ideas?

Thanks in advance.
