Thanks, imparanoic. I appreciate the tip on the Yorter/Oregon brand. I picked up the EM913 model at Wah Kiu Radio Co (across the street from Central Market) for $178.
most hygrometers with electronic sensor have a tolerance of +/- 10% which is more than adequate for household use. these do have to be calibrated every 2-3 years.
go for a for mechanical sensor, its cheaper and more accurate.
