Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Hygrometers
These are the gold standard for relative humidity measurement. Not very convenient, but simple and accurate. Instruction manual dated mid-'80s. Identical product is still manufactured in this country, so parts are available, but with care the wick is the only part that should ever need replacement. Mine arrived with one of the spirit thermometers separated (useless), but the mercury thermometers were perfectly matched, so it's a great instrument (and I have to be careful not to break the thermometers).
