Best hygrometer

[DSpythons]

Any dial type hygrometer with a metal faceplate and calibration knob will work. These are very different from the junk sold in pet stores that have cardboard faceplates and cannot be calibrated.

These can be hard to find, but they are available. I would post a link but the site I got mine from does't exist any longer.

Would this work? I know the pet store ones are junk. I saw some one post a metal one before that is supposed to be very accurate.
