Title: Hyrgometer does not work - twice!
Review: It stinks. The first one I got showed more than 20% lower R.H. than a honeywell I was using. I tried the Salt Water test to calibrate, and it showed the Timex was 20% - 25% too low. Amazon sent me a replacement for free (nice of them). The replacement didn't work either. I'm sending back for a refund. Don't waste your time with this.
