Rated 3 out of 5 by from Problems with calibration RH92 Psychrometer. The RH92 Digital Psychrometer Is easy to use when measuring the environmental relative humidity and dew point. However, the psychrometer sensor is too small to fit snugly into the calibration salt containers so there is no accurate calibration possible for the psychrometer. I am waiting for Omega to correction the problem.

Rated 4 out of 5 by from Nice piece of equipment Although the gauge I purchased was a more low end product I expected a bit more, at least the "Omega" name to be identified on it, which it was not.
