The Davis Instruments Turbo Meter Wind Speed Indicator measures wind speed from 0 - 99 MPH and is accurate to +/- 3%. The rotation of the freely turning turbine on the Davis Instruments Turbo Meter Wind Speed Indicator, suspended on sapphire jewel bearings, is sensed by an infrared light beam. The resulting signal is processed electronically. The display is large and bright for excellent viewing in full sun or dark conditions. The Davis Instruments Turbo Meter Wind Speed Indicator includes a Auto Power-Off feature, is compact in size and lightweight. Wrist lanyard, protective case included.
