The Comfort Guide Hygrometer measures the temperature and the relative humidity in the air. Indoor heating can rob moisture from the air, so even comfortable temperatures leave skin dry and increase susceptibility to illness. The proper mix of temperature and humidity prevents chapped lips, parched throat and cracked skin.
* Measures temperatures between -50 and 160 degrees.
* Measures humidity between 20 and 90 percent.
