Yes, it is entirely possible for a digital or analog hygrometer to be off by 16 or 17 points (or more). The technical term for such a hygrometer is "junk"- my garbage man has been the recipient of several fine examples of "junk" hygros.

My little $20 hygros came from Radio Shack, but I think they quit offering them, so you might try Basil's site.

Good luck
