Product review (1 stars): Inaccurate readings and no way to calibrate
Unfortunately, the thermometer was inaccurate and was about 2-3F degrees off the correct temperature. There was no way to calibrate it.  What made things worse is that the humidity was stuck at 20% and didn't move at all for several days, despite the other thermometers in the room changing their reading as the humidity went up and down throughout the day.  I am usually a fan of Accurite, but this product in my view is one of their weakest offerings.
