The 08856 Acu-Rite Humidity Gauge is an indoor hygrometer that rests on a desktop, table, shelf, or countertop. This dial-type analog instrument indicates both the relative humidity in percent and the corresponding comfort range: Very Dry, Dry, Normal, or Humid. Use the 08856 in your home, office, greenhouse, or any other indoor location where you want to know the humidity at a glance.

The 08856 desktop hygrometer is preset and needs no calibration. All that it requires before use is an initial "moisture charge." You simply place the instrument on its back on a warm, wet cloth and leave it for several minutes. Be sure that the pointer moves above 80%. If the hygrometer becomes inaccurate over time, simply perform another moisture charge.

It is the nature of humidity meters like the 08856 to respond slowly, so it takes time to produce an accurate reading. For maximum accuracy, do not locate the 08856 near an air conditioner, heat register, vaporizer, fireplace, or anything else that can affect humidity. According to the product's package, "normal" winter readings should range from 30% to 35%.

The 08856 Desktop Humidity Gauge is designed for free-standing use only. It cannot be wall-mounted. The 08856 is covered by a manufacturer's 1-year limited warranty.
