Humidity & Temperature Control
Humidity is the amount of water vapor in the air. In daily language the term "humidity" is normally taken to mean relative humidity. Relative humidity is defined as the ratio of the partial pressure of water vapor in a parcel of air to the saturated vapor pressure of water vapor at a prescribed temperature. Humidity may also be expressed as absolute humidity and specific humidity. Relative humidity is an important metric used in forecasting weather. Humidity indicates the likelihood of precipitation, dew, or fog. High humidity makes people feel hotter outside in the summer because it reduces the effectiveness of sweating to cool the body by preventing the evaporation of perspiration from the skin. This effect is calculated in a heat index table.

Hygrometers are instruments used for measuring humidity. A simple form of a hygrometer is specifically known as a "psychrometer" and consists of two thermometers, one of which includes a dry bulb and the other of which includes a bulb that is kept wet to measure wet-bulb temperature. Evaporation from the wet bulb lowers the temperature, so that the wet-bulb thermometer usually shows a lower temperature than that of the dry-bulb thermometer, which measures dry-bulb temperature. When the air temperature is below freezing, however, the wet bulb is covered with a thin coating of ice and yet may be warmer than the dry bulb. Relative humidity is computed from the ambient temperature as shown by the dry-bulb thermometer and the difference in temperatures as shown by the wet-bulb and dry-bulb thermometers. Relative humidity can also be determined by locating the intersection of the wet- and dry-bulb temperatures on a psychrometric chart. One device that uses the wet/dry bulb method is the sling psychrometer, where the thermometers are attached to a handle or length of rope and spun around in the air for a few minutes.

Dry Climate: Humidifiers are key to keeping your acoustic in good condition if you live in a dry climate. Acoustic guitars can and will shrink and/or crack when exposed to super dry climates, like here in Las Vegas or other desert environments. If although, you live in the desert and have had an acoustic for 10 years that hasn't cracked, then you very likely won't need a humidifier to protect it from cracking. You may be surprised though, what restoring a bit of moisture to the wood will do for the tone of the instrument.
If you store your instrument in its case this humidifier will be helpful. Submerse it in water for 5 minutes and wipe off excess, then store it in your case. Repeat twice a month. Works for guitars, violins, cellos, clarinets or any other fine wooden instrument.
Editor's Note: (Feb 2007) This is the humidifier that I'm using for my ukuleles.
This humidifier is available at most any music store or online. Elderly Instruments has them discounted.
