Over the years I have tried multiple brands of digital hygrometers and while most seem fairly close when doing a saturated salt test, some are off more than a few percent when they should read 75% in a salt test. Even those which are only a few percent off seem to get increasingly off as I periodically test them again over the year. Has anybody found a model that has proven reliable? I have read articles saying the salt test is fairly accurate over a fairly wide range of temperatures, but the whole idea of RH is percentage of moisture air will hold at a given temperature. So, a sealed container of air may be 70% RH at 70 degrees. If you lower the temperature to 65 degrees the RH becomes 83%, because cold air does not have the ability to hold as much moisture before condensation occurs. So I wonder, if the hygrometer is inaccurate 1-5 percent and the temperature is not right on 70 degrees, are these gauges just ball park accurate at best? We may be creating a false confidence. My theory is that it is better to be off to the dry side in order to prevent mold and cigars that won't burn well. Should the salt test value be adjusted to temperature and not be simply 75%?
