Which one should I trust? Is there a way to visual judge? I have 2 thermometers/hygrometers (1 analog and 1 digital). Days 1-17...They held a temp with a .5 difference, and the humidity was calibrated and they remain matching to each other accordingly. But I removed the egg trays to get ready for lock down. Put both thermometers/hygrometers back in (the same spots they were in originally), and they are totally off with both after several hours. The thermometer is off by 6 degrees. (Analog thermometer is reading lower now and I haven't adjust the temp. Digital reading the same) The hygrometer is off by 12 degrees between the two according to original calibration calculations. (digital is at 65 and analog is at 77 now) I don't know which one to trust. Why would there be such a jump all the sudden? I don't have time to calibrate, I need to put them in lock down.
