digital hygrometer suggestions??

[Grant vg]

For those of you who keep many high humidity animals, what type of system do u have set up so that u can regulate all your animals accurately and easily.
Im thinking of investing in many small digital hygrometers, as i think that is the only way i can see it happening.
(unless someone invents a humidity gun)

Any suggestions on a good, moderately priced digital hygrometer?
i need a dozen or so...

Or does anyone have a good system they use.
Right now, im placing the couple of hygrometers i have in each enclosure for a short period to get a reading, however, its too time consuming.

Thanks for any imput.
