La Crosse EA-3010
Portable Hand-Held Anemometer

The La Crosse EA-3010 Portable Hand-Held Anemometer is a practical and economical choice for people who enjoy outdoor activities in a wide range of weather conditions and want or need to know the wind speed plus the temperature and wind chill factor. With only two buttons to push, the EA-3010 is exceptionally easy to set up and use. The MODE button turns the instrument on and off and also selects the main operating mode, either wind speed or temperature. Within an operating mode, you push the + button to toggle between the available display options. It's that easy!

The Beaufort wind scale bar graph is continuously displayed in both the wind speed and temperature modes and reads from 0 (Calm) to 12 (Hurricane). For each numeric wind force indication, a handy table in the instruction manual gives the description (such as Fresh Breeze or Strong Gale) and the corresponding wind speed in all 4 displayable measuring units.

In the temperature mode, the EA-3010 can display the current temperature or current wind chill. During setup, you can select either °F or °C for these readings.

One particularly nice feature of this pocket anemometer is the condensed set of instructions printed on the back of the instrument. Another is the LCD panel backlight with 8-second auto-off. Still another is the included detachable lanyard so you can wear the EA-3010 around your neck if you wish.

Although the EA-3010's case is weather-resistant, this instrument is not submersible.

The EA-3010 is powered by one CR2032 (3V) lithium battery, which is included and preinstalled. To maximize battery life, the anemometer automatically turns itself off after 34 minutes if no button is pressed during that time. For reliability, the manufacturer recommends that you replace the battery annually. 

Please note that anemometers of this type are sensitive to magnetic fields. These instruments work by picking up magnetic impulses transmitted by the spinning impeller blades, processing them into logic pulses, and supplying them in binary form to the LCD panel. This means that the instrument may display numeric values when in a magnetic field (from a computer, electric appliance, etc.). However, this will not affect operation under normal circumstances.
