Rated 4 out of 5 by mgangler from Good tolerance for the money We have used these in the past, they are not adjustable should they fail calibration. We have moved to the RH92, not as accurate but adjustable and less expensive. Know your application before purchasing.

Rated 5 out of 5 by jlcomposites from just what you expected Works perfectly. Note that the C, F, and APO options are switches, not buttons. So, you need to pry out the rubber strip to access them.

Rated 5 out of 5 by DWH46 from Useful Instrument Assuming that the calibration of the instrument is correct -- the device provides exceptional value in monitoring RH. The directions provided could be made less ambiguous and more detailed. But, experimentation with the device can resolve the uncertainties.
