Im measuring it with a extech psychrometer. It take surface readings relative humidity ambient temps wet bulb dew point etc. I know its accurate it is used for my work and has to be calibrated every three months. And the uth is stuck directly to the bottom of the glass just using the peel and stick backing that was on it.
