What Is a Hygrometer?

A hygrometer is an instrument that measures humidity. It's also an essential device at every level of meteorology. Hygrometers in Brief The simplest varieties are just two thermometers, one in water and the other in air. The water thermometer naturally has a cooler reading. The dry thermometer measures ambient air temperature. By simply taking the difference between the readings, the relative humidity is easy to calculate.

Modern Hygrometers

Although weather specialists still use analog hygrometers, digital models are fast replacing their older cousins. The difference is in their versatility.

• Analog: These classic hygrometers resemble wall-mounted clocks. Instead of time, the face reads temperature and humidity.
• Digital: The latest hygrometers are small, lightweight, and blessed with wireless capability. A reading taken in one place is easily sent elsewhere.

More Digital Advantages
At as little as $20 for a basic digital hygrometer, they are also quite affordable. Also, a digital hygrometer may also come with some especially handy extras including:

• Time/Date functions
• Interval data reading/tracking
• Barometer
• Indoor/Outdoor humidity reading
• GIS/GPS enabled (important for mapping functions)
• Weather forecasting capabilities
