Measuring principle

The digital anemometer measures wind speed by measuring the speed of the fan(vane), whose axis is parallel to wind direction, using a revolution counter and converting it into readable format. 

Applications 

An anemometer is a device used for measuring wind speed with additional features of wind direction, temperature and relative humidity. It is a common instrument in weather stations, metrological departments and checking air conditioning and heating systems.

 

Features

• Built in temperature measurement.
• A sensitive balance vane wheel rotates freely in response to air flow.
• Reading convertible to different measurement units.
• Data memory for storing and recalling values later.
• Data hold and auto power off.
• Backlit display.
