Anemometers and psychrometers are both instruments used in meteorology, but they measure different atmospheric variables:
-
Anemometer: This device is used to measure wind speed and sometimes wind direction. It can help determine how fast the wind is blowing, which is crucial for weather forecasting, aviation, and various engineering applications.
-
Psychrometer: This instrument measures humidity in the air. It typically consists of two thermometers: a dry bulb thermometer and a wet bulb thermometer. The difference in their temperatures can be used to calculate relative humidity and dew point.
In summary, anemometers measure wind speed, while psychrometers measure humidity.
