Most accurate thermometer?

  1. I was comparing two different thermometers w/hygrometers today. And got some interesting results. While both showed indoor temperature with 1.5 degree of difference, the RH was way off. The National Geographic thermometer showed RH of 34, while ActiveAir thermometer showed RH of 25. What gives?

    Any suggestions on a more accurate thermometer w/hygrometer? Should I go old school analog?
