TFA Dostmann anemometer 0 til 30 m/s (42.6001.01)

Outdoor enthusiasts, sailors, and HVAC technicians can accurately measure wind speed and temperature with this compact anemometer. The impeller sensor responds within about a second, and the backlit LCD clearly shows readings in m/s, km/h, mph, knots, or Beaufort. A built-in thermometer displays ambient temperature in °C or °F, while max/min/average wind speed and wind chill functions help you assess conditions at a glance. The device automatically powers off after 14 minutes of inactivity to conserve the CR2032 battery.
